Safety belt guide
The present invention relates to a belt guide for a safety belt.
Safety belts have become an indispensable safety means, particularly in vehicles, with which a passenger can secure him/herself in a seat. These were initially so-called two-point belts which ran only over the hip of the person, but nowadays passenger cars are embodied mainly with three-point belts which, in addition to extending over the hip, also extend from the hip over the shoulder region of the person. In order to increase the comfort of such three- point belts, automatic locking retractors are usually provided which allow the person sufficient freedom of movement in safe situations, but which lock in the case of a collision, and, optionally supported by a belt tensioner, confine the person firmly in the seat.
Although three-point belts have undeniable advantages in respect of the safety of the passenger, they do however also have drawbacks. Particularly in the case of a severe collision and a strongly gripping belt tensioner, chest injury not infrequently occurs because of a locally squeezing belt. In the case of the female population, the shoulder belt of a three- point belt also runs continuously over one of the two breasts, and this is often perceived as irritating.
The present invention has for its object, among others, to provide a safety belt guide which obviates these and other drawbacks to an at least significant extent.
A belt guide for a safety belt according to the invention is for this purpose characterized by an elongate, at least substantially form-retaining body which comprises end parts on either side, respective longitudinal axes of which are oriented at least substantially parallel to each other, and by a transition part which lies between the two end parts and a longitudinal axis of which forms an angle with the two above mentioned longitudinal axes, wherein both end parts are provided with fastening means for fixing the safety belt, and wherein the transition part is provided with guide means for carrying the safety belt at least substantially along the transition part from the one end part to the other end part. The belt guide is applied at breast
height and herein guides the shoulder belt of a three-point belt between the two breasts. The squeezing of the breast by the belt that is perceived as unpleasant is thus avoided, or at least countered to a significant extent.
In a preferred embodiment, the belt guide according to the invention has the feature that the body comprises a sleeve with a central cavity which extends via the transition part from the one end part to the other end part, and that the cavity is intended and adapted for receiving therein a part of the safety belt. In this case the guide is slid as a sleeve o^ver the shoulder belt to guide the safety belt in the desired path along the full length.
In order to allow the belt guide to be still arranged easily, also after the safety belt has been fitted, a further prefened embodiment of the belt guide according to the invention has the feature that the sleeve is provided over the whole length thereof with fastening means for manual opening. The sleeve does not in this case have to be pushed beforehand over the belt, wherein the belt would then have to be taken off, but owing to the fastening incorporated therein it can be ananged round the belt easily in an existing situation. In a further embodiment the belt guide herein has the feature that the fastening means are taken from a group comprising a zip fastener, an adhesive fastening and a velc-ro fastening.
In order to interfere as little as possible with the normal progression of thie shoulder belt of a three-point belt, a further particular embodiment of the belt guide according to the invention has the feature that both end parts lie at least practically in line with each, other.
The invention will be further elucidated hereinbelow with reference to an exemplary embodiment and an accompanying drawing. In the drawing:
figure 1 shows a front view of the use of a belt guide according to an exemplary embodiment of the invention; and figure 2 shows a front view of the belt guide of figure 1 in opened position. The figures are otherwise purely schematic and not drawn to scale. Some dimensions in particular may be exaggerated to a greater or lesser extent for the sake of" clarity.
Corresponding parts are designated as far as possible in the figures with the same reference numeral.
Figure 1 shows schematically a breast region of a female user 1 during use of a so-called three-point belt 2 in a vehicle. Such a safety belt 2 comprises a lap belt 21 in combination with a shoulder belt 22 which runs diagonally from one of the two hips to the shoulder. It is particularly this latter belt which is perceived by female users in particular as irritating because it exerts pressure on the breasts.
In order to counter this, the invention provides a belt guide 3 which at the location of the breast region guides the belt 2 in a path running between the two breasts instead of over them. To this end the belt guide comprises a substantially from-retaining body of, in this embodiment, padded textile having on either side an end part 31,32 for receiving or releasing the shoulder belt 22. Both parts 31,32 herein have respective longitudinal axes 41 ,42 which substantially run mutually parallel and are connected to each other by a transition part 33. A longitudinal axis 43 of the transition part herein forms an angle with the two other longitudinal axes. The two end parts 31,32 thus open practically in line with each other, while transition part 33 guides the belt 22 in a relatively steep path between the two breasts.
Although the belt guide according to the invention can be embodied in many ways, use is made in this embodiment of a body in the form of a sleeve with a central cavity which extends from the initial part 31 to the end part 32 to receive the belt 22 therein along its full length. The cavity thus fixes the belt in or at the initial and end part, and the cavity carries the belt in the desired path via transition part 33. In order to enable simple arrangement of the belt guide in an existing situation, the body is manually releasable on a side directed toward the user, referred to below as the rear side. Figure 2 shows the opened situation wherein the rear side comprises two individual flaps 34,35 which can be readily trained round an existing belt. On their outer end the two flaps 35,36 comprise fastening means 37,38 for securing the whole once it has been arranged. The fastening means comprise here a so-called hook and loop or Velcro® fastening, but may also be embodied otherwise, for
instance as button or zip fastening. Once the belt guide has thus been arranged, "the guide can, if desired, be slid over belt 22 so as to be thus placed in the correct position-. In this position the belt guide leads the safety belt in a relatively steep path between the two breasts so that a squeezing pressure thereof on the breasts is avoided.
Although the invention has been further elucidated above on the basis of only thie one exemplary embodiment, it will be apparent that the invention is by no means limited thereto. On the contrary, many variations and embodiments are still possible within the scope of the invention for the person with ordinary skill in the art. For the material of the beLt guide a stronger material can thus be applied instead of textile, in particular a plastic such as for instance polyethylene, polyvinyl chloride or nylon. Instead of being a continuou-.s sleeve, the body can also have a more open structure wherein at designated points the belt £s fixed thereto for instance by means of freely accessible clips and is thereby guided in the desired path. In this case a separate fastening on the rear can be omitted in some cases without losing convenience of use. The invention provides an effective increase in the nearer comfort of a safety belt, particularly for female users, which can be realized in many ways.
