WO2022211670A1 - Adjustable bicycle seat - Google Patents

Abstract

Field of use: mechanical and electric bicycles, exercise bicycles. Problems solved: uneven support of the seat bones, hunching of the back and constriction of the vessels in the perineum when riding a bicycle with a standard seat. Essence of the utility model: to improve the anatomical and ergonomic characteristics and the comfort of any type of bicycle by allowing tailored adjustment of the seat to the size and individual characteristics of the user's pelvis. The seat consists of a seat body having a central part (1), two identical adjustable parts (2, 3) arranged on the seat body on opposite sides of the central part, and a mechanical or electrical adjustment device (4), built into the seat body, for moving the adjustable parts. The distance can be increased from 113 mm to 144 mm.

Description

Description of the useful share.

Utility Model Name: Sliding Bicycle Seat.

Scope: Mechanical and electric bicycles, exercise bikes. BACKGROUND OF THE INVENTION: There is a large variety of bicycle saddles for different types of bicycles, with classic seats, comfortable and ergonomic seats, and one resizable seat.

The claimed utility model improves the anatomy, ergonomics and comfort of using any type of bicycle by changing the size of the seat to fit the dimensions and features of the pelvis of a particular person.

Given that (according to PeopleSize 2020 statistics, htp://www.openerg.com), the average size between the ischial tuberosities in men is 118 mm, in women it is 130 mm, the proposed useful model of a sliding bicycle seat is suitable for approximately 70% of the male and female population of the planet.

The adjustment possibilities of the proposed sliding bicycle seat allow you to set the width to the most suitable for the particular pelvis of a particular person, which eliminates constant pressure on the perineum and reduces the likelihood of spinal curvature.

The object of this utility model is a seat for bicycles or exercise bikes with adjustable width. The seat of this utility model consists of a body with a central part (pos. 1), two identical sliding parts (pos. 2, 3) placed on the seat body on opposite sides of the central part and a mechanical or electrical regulator (pos. 4) built into a body that provides movement of the sliding parts (figure 1). Two sliding parts of the seat (pos. 2, 3) are located symmetrically relative to each other, on opposite sides of the central part (pos. 1). By pressing the latch (b) of the seat adjuster (item 4), the latch (b) is lowered below the mating part of the latch (c), which releases the adjuster connector (a), which in this state can move along the central part of the seat body (item 1 ) back and forth on the mating part (c) of the regulator connector (a). The regulator connector (a) has connector protrusions (d) on its surface, which, moving along the channels (pos. 5) of the sliding parts of the seat (pos. 2, 3), set them in motion (figures 2 and 3).

When the regulator connector (a) moves, its protrusions (d) exert pressure on the walls of the channels (pos. 5), which causes the moving parts of the seat (pos. 2, 3) to shift relative to the central part (pos. 1).

Moving the seat adjuster connector (a) toward the rear relative to the current adjuster position will cause "out" pressure in the channels (key 5) and move the moving parts (keys 2, 3) away from the center of the seat (key 1).

Moving the seat adjuster connector (a) towards the front relative to the current position of the adjuster will cause “inward” pressure in the channels (key 5) and move the moving parts (keys 2, 3) towards the center of the seat (key 1).

When the desired displacement of the moving parts of the seat (pos. 2, 3) is reached, it is necessary to stop pressing (release) the regulator latch (b), the latch (b) will rise to the level of the mating part of the latch (c), which will fix the regulator connector (a), which in this state, it cannot move along the central part of the seat body (pos. 1).

With the maximum displacement of the seat adjuster (pos. 4) towards the rear (Fig. 4), the distance between the points of placement of the ischial bones will be 113 mm.

With the maximum displacement of the seat adjuster (pos. 4) to the front (Fig. 3 - the maximum extended seat), the distance between the placement points of the ischial bones will be 144 mm. Industrial applicability: the claimed utility model can be manufactured at any industrial enterprise using well-known, widely used technologies. Seat materials (metals and plastics) are widely available on the market, and their characteristics can change the strength, weight and service life of the model, while maintaining the principles of operation of the sliding seat. The selection of manufacturing technologies and materials can be carried out in relation to the equipment of the manufacturer.

Novelty: At the time of filing the application, no patents or utility models for a sliding bicycle seat were registered that are valid on the territory of the Russian Federation.
