Description

Seat

The present invention relates to a seat, particularly to a fixing structure of a trim to a cushion pad.

For seats such as automobile seats, cushion pads made of resin material are covered with trim made of leather or vinyl leather in the seat cushions that support the buttocks of the seated person and the seat backs that support the back of the seated person. The structure is adopted. The trim is fixed to the cushion pad on the back surface of the cushion pad (the surface opposite to the side where the buttocks and back touch).

Patent Document 1 discloses a structure in which the end edge portion of the trim is fixed to a seat frame integrally molded with the cushion pad on the back surface of the cushion pad by using an ohm clip.

Further, in Patent Document 2, on the back surface of the cushion pad, the cushion pad is formed by pushing a fastener having a rod-shaped tip and a trim end edge fixed to the hole provided in the cushion pad. The structure in which the trim is fixed is disclosed.

Japanese Unexamined Patent Publication No. 09-276091 Japanese Patent No. 6107460

However, with the structure disclosed in Patent Documents 1 and 2, it is difficult to fix the trim to the cushion pad with high workability. Specifically, in the structure disclosed in Patent Document 1, it is necessary to use a hook ringer when attaching the ohm clip to the seat frame, but the hook ringer is heavy and workability is not good.

Further, in the structure disclosed in Patent Document 2, in order to prevent the fastener pushed in from the hole provided in the cushion pad from easily coming off, the width of the iron-shaped portion at the tip of the fastener is larger than the width of the hole. It needs to be large and requires a large force when pushed. Therefore, even with the structure disclosed in Patent Document 2, it is difficult to fix the trim with high workability. Further, when the end user replaces the trim, the iron-shaped portion of the fastener needs to be removed from the cushion pad, but the iron-shaped portion disclosed in Patent Document 2 does not have flexibility, and the iron-shaped portion is not flexible. If you try to remove it from the cushion pad, the cushion pad will be scraped off by the corners of the iron-shaped part. Therefore, it becomes impossible to fix the iron-shaped portion to the hole again, and there is a possibility that the entire cushion pad must be replaced.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a sheet having a structure in which a trim can be attached to and detached from a cushion pad with high workability.

The seat according to one aspect of the present invention includes a cushion pad having a support region for supporting the occupant, a region other than the support region and having a hole provided in the thickness direction, and the cushion pad. The covering area covering the support area, the trim having the edge portion arranged in the vicinity of the hole portion, and the edge portion of the trim are fixed and inserted into the hole portion to obtain the said. A clip for fixing the trim and the cushion pad is provided, and the clip is continuous with the trim fixing portion to which the end edge portion of the trim is fixed and the trim fixing portion, and the inside of the hole portion of the cushion pad. A plate-shaped base portion to be inserted into the base portion, one end thereof is continuous with the base portion, the other end is a free end, and the base portion is inserted into the hole portion together with the base portion while being along the base portion. It has a flexible pressing portion, and the pressing portion is inserted into the hole portion together with the base portion so that the portion on the other end side of the one end bends toward the base portion. By deforming, an outward pressing force is applied to the first side wall surface of the hole portion with which the pressing portion abuts.

The detailed structure of the clip 13 will be described later.

3. 3. Structure of Clip 13 The structure of the clip 13 will be described with reference to FIGS. 5 and 6.

As shown in FIG. 5, the clip 13 has a long shape in which the dimension L13 in the Y direction is longer than the dimension in the X direction and the dimension in the Z direction. The dimension L13 is, for example, 50 mm to 150 mm. As shown in FIGS. 5 and 6, the clip 13 is integrally formed with a trim fixing portion 13a, a base portion 13b, a pressing portion 13d, and a return portion 13g. The clip 13 is formed using, for example, polypropylene.

As shown in FIG. 6, the trim fixing portion 13a and the base portion 13b are formed so that one end in the X direction of the trim fixing portion 13a and one end in the Z direction of the base portion 13b are continuous. The trim fixing portion 13a has a width of W13 in the X direction and a thickness of T1 in the Z direction. The height of the base portion 13b in the Z direction is H13, and the thickness of the base portion 13b is T2 in the X direction.

The dimensions are, for example, a width W13 of 15 to 20 mm, a thickness T1 of 1 to 4 mm, a height H13 of 15 to 20 mm, and a thickness T2 of 1 to 4 mm. In this embodiment, as an example, W13 = 17.4 mm, T1 = 2 mm, and H13 = 18.8 mm.

The pressing portion 13d is formed so that one end 13i in the Z direction of the pressing portion 13d is continuous with the bottom end 13c of the base portion 13b in the Z direction. The pressing portion 13d has a first curved portion 13j and a second curved portion 13e. The first curved portion 13j is formed in a curved shape so as to be separated from the base portion 13b as it goes from one end 13i toward the side of the trim fixing portion 13a in the Z direction (upper side in FIG. 6).

The second curved portion 13e is continuous with the first curved portion 13j at the end of the first curved portion 13j (the end on the trim fixing portion 13a side), and is on the side of the trim fixing portion 13a in the Z direction (FIG. 6). It is formed in a curved shape so as to approach the base portion 13b as it goes to the upper side).

The end portion 13h of the second curved portion 13e on the side of the trim fixing portion 13a in the Z direction (upper side in FIG. 6) is not connected to the trim fixing portion 13a, the base portion 13b, or the like. When no external force is applied to the pressing portion 13d (the state shown in FIG. 6), there is a gap G1 between the pressing portion 13a and the trim fixing portion 13a, and a gap G2 between the pressing portion 13d and the base portion 13b. It has become.

As shown in FIG. 6, the second curved portion 13e is formed so that the other end 13h of the second curved portion 13e points in the direction indicated by the arrow B. The direction indicated by the arrow B is the direction toward the trim fixing portion 13a and the base portion 13b side.

Here, in the clip 13 according to the present embodiment, the other end 13h of the pressing portion 13d is formed with a curved surface.

In a state where no external force is applied to the pressing portion 13d (state shown in FIG. 6), the boundary portion P13d between the first curved portion 13j and the second curved portion 13e is the farthest from the base portion 13b. The distance from the outside of the base portion 13b to the outside of the pressing portion 13d at the location P13d is W13d. The distance W13d is set in relation to the groove width of the groove portion 11c (see FIGS. 3 and 4) provided in the cushion pad 11, but in the present embodiment, for example, 5 to 10 mm (as an example). 6.5 mm).

Further, the maximum thickness of the pressing portion 13d is T3. The thickness T3 is set thinner than the thickness T2 of the base portion 13b. In this embodiment, as an example, T3 = 1.2 mm. By making the thickness T3 thinner than the thickness T2 in this way, when the base portion 13b and the pressing portion 13d are inserted into the groove portion 11c, the pressing portion 13d is pressed by the arrow A due to the reaction force from the side wall surface of the groove portion 11c. It can be reliably bent as shown.

Further, a recess formed in the vicinity of the bottom end 13c of the base portion 13b, in other words, in the connecting portion between the base portion 13b and the pressing portion 13d so as to be thinner than the other portions in the base portion 13b. The entrance 13f is formed. By forming the recessed portion 13f, the pressing portion 13d can be easily bent as shown by an arrow A starting from the portion where the recessed portion 13f is provided. The flexibility of the pressing portion 13d can be adjusted depending on the degree of recessing, in other words, how thin the thickness of the recessing portion 13f is.

The return portion 13g protrudes from the vicinity of the bottom end 13c of the base portion 13b toward the side opposite to the side on which the pressing portion 13d extends (on the right side in the X direction in FIG. 6), and the tip is sharp. The return portion 13g has a plane whose upper surface in the Z direction is substantially parallel to the trim fixing portion 13a. The amount of protrusion of the return portion 13 g is W13 g. The protrusion amount W13g is, for example, 1 to 2 mm, and in the present embodiment, as an example, W13g = 1.5 mm.

4. Fixing the Trim 12 to the Cushion Pad 11 Fixing the trim 12 to the hard pad 111 in the cushion pad 11 will be described with reference to FIG. 7.

As shown in FIG. 7, the edge portion 12a of the trim 12 is fixed to the trim fixing portion 13a of the clip 13. Although not shown in FIG. 7, the trim fixing portion 13a is formed in a long shape along the groove portion 11c (see FIG. 5), and the trim 12 is formed in a plan view from the Z direction. It is fixed to the trim fixing portion 13a at a position extending linearly along the longitudinal direction of the trim fixing portion 13a.

The clip 13 is fitted into the groove portion 11c by a worker by hand so that the bottom end 13c of the clip 13 faces the groove bottom 11i side without using a special tool.

When the base portion 13b and the pressing portion 13d of the clip 13 are pushed into the groove portion 11c, a part of the base portion 13b and the pressing portion 13d of the clip 13 comes into contact with the side wall surfaces 11f and 11g of the groove portion 11c. Then, the pressing portion 13d that receives the reaction force from the side wall surface (first side wall surface) 11f bends in the X direction (direction toward the side wall surface (second side wall surface) 11g). In the clip 13, the base portion 13b also bends slightly, but the pressing portion 13d mainly bends due to the difference in thickness between the base portion 13b and the pressing portion 13d and the formation of the recessed portion 13f.

Then, as shown in FIG. 4, when the bottom end 13c of the clip 13 reaches the vicinity of the groove bottom 11i, the trim fixing portion 13a of the clip 13 is attached to the back surface 11b (outer surface of the hard pad 111) of the cushion pad 11. Contact or close. At this time, the portion P13d in the pressing portion 13d of the clip 13 and the portion in the vicinity thereof (the portion indicated by the arrow C) are fitted into the recessed portion 11d (the portion indicated by the arrow D) provided on the side wall surface 11f of the groove portion 11c.

Further, since the constituent material of the clip 13 is polypropylene, which is harder than the hard pad 111 made of bead foam, the return portion 13g (the portion indicated by the arrow E) of the clip 13 is located on the side wall surface (the portion indicated by the arrow E) in the vicinity of the groove bottom 11i. Second side wall surface) engages with 11 g. More specifically, the return portion 13g penetrates outward from the side wall surface 11g until the base portion 13b abuts or approaches the side wall surface 11g.

In a state where the base portion 13b and the pressing portion 13d of the clip 13 are pushed to the state shown in FIG. 4, the pressing force acts on the side wall surface 11f from the pressing portion 13d, and the pressing force acts on the side wall surface 11g from the base portion 13b. .. As a result, the trim 12 is fixed to the cushion pad 11.

As described above, when adopting a configuration in which the trim extends beyond the one end of the trim fixing portion to the outside of the trim fixing portion and the extending portion continues to the covering area, the operator trims the trim. Tension can be applied to the trim by gripping one end or side end of the fixed portion and moving the clip to the portion provided with the hole. Therefore, it is advantageous in ensuring high workability while making it difficult for wrinkles to occur in the covered area.

In the sheet according to the above aspect, the trim may be fixed to the trim fixing portion at a portion extending linearly along the one end portion of the trim fixing portion.

As described above, if the trim fixing portion in the trim fixing portion extends linearly in the above direction, the degree of pulling of the trim is unlikely to be uneven. Specifically, in the structure disclosed in Patent Document 1, the trim is fixed to the seat frame by using an ohm clip. Then, the trim is fixed at the points where the fixing points to the seat frame are arranged at intervals from each other. Therefore, in the structure disclosed in Patent Document 1, it is conceivable that wrinkles occur because the degree of pulling of the trim is uneven.

On the other hand, as described above, if the trim fixing portion in the trim fixing portion is extended linearly, the degree of pulling of the trim is less likely to be uneven, and the occurrence of wrinkles is suppressed.

As described above, in the seat according to each of the above aspects, the trim can be attached to and detached from the cushion pad with high workability.

Further, in the sheet according to each of the above aspects, the clip can be removed from the cushion pad while preventing damage to the cushion pad, and the trim can be easily replaced.
