Abstract

PROBLEM TO BE SOLVED: To secure desired wideness in a cabin without enlarging the car width as there is no need for the attachment of any shock absorber to a side door and of forming this side door into a shock absorbing structure capable of forming it into a less shock absorber with a simple structure. SOLUTION: A shock absorber 6 constituting a part of a seat back 3 is installed in a side face at the side of a side door 15 of this seat back 3. At a time when an automobile gets a side collision and the side door 15 or a floor 30 is deformed, a shifting means 12 actuates along with this deformation, shifting the shock absorber 6 into a gap between an occupant 16 and the side door 15. With thismovement, any impact being given to the occupant 16 is absorbed by the shock absorber 6. In addition, normally, since a shock absorbing member is set up in the rear of the occupant, it will not be hindered to the occupant at all and, what is more, it will not be obstructed to his sight.

で吸収する。In order to solve the above-mentioned problems, the first aspect of the present invention is to provide a shock absorber for absorbing shock energy on the side portion of the seat back on the door side, and to install the shock absorber on the door side of the seat. A moving means for moving the shock absorber between the occupant of the seat back and the door when the door or the floor is deformed by an impact is provided on the side portion or the floor supporting the seat. As described above, the impact absorber forming a part of the seat back is provided on the door side of the seat back. Then, when the door collides with the side surface of the vehicle and the door or the floor is deformed, the moving means is actuated in accordance with the deformation to move the shock absorber between the occupant of the seat back and the door. As a result, the impact applied to the occupant is absorbed by the impact absorber.

ているので右側後部については説明を省略する。As a result, the left rear portion of the seat cushion 13 is supported on the outside of the seat rail 28 while being offset by (L 2 + L 3 ). Further, the support plate 29 in this case is supported at the height position of H 2 . Although the case where the left rear portion of the seat cushion 13 is supported has been described with reference to FIG. 13, the right rear portion is also fixed in the same manner as the left rear portion, and therefore the description of the right rear portion is omitted.

FIG. 14 is an explanatory view showing the left front end of the seat cushion after the impact of the fifth embodiment according to the present invention. When the impact force F acts on the side door 15 side of the automobile, the floor 30
The floor 30 is bent in a substantially V shape from the notch 30a formed at the left end of the. Thereby, the front side angle 26 inclines inward. In this case, as shown in FIG. 12, the left front end of the seat cushion 13 is L inside the seat rail 28.
Since it is offset by 1 minute, the support plate 29 descends from the height position of H 1 by h 1 . Therefore, the left front end of the seat cushion 13 descends from the normal position by h 1 .

Similar to FIG. 14, when the impact force F acts on the side door 15 side of the automobile, the floor 30 is bent in a substantially V shape from the bending position 30b at the left end portion of the floor 30. As a result, the rear angle 27 is inclined inward. In this case, since the left rear end of the seat cushion 13 is offset to the outside of the seat rail 28 by L 2 as shown in FIG. 13, the support plate 29 rises from the height position of H 2 by h 2 . Therefore,
The left rear end of the seat cushion 13 rises from the normal position by h 2 minutes. Furthermore, the mounting portion 33 offset by L 3
Rotation causes h 3 to rise.

ることができる。As shown in (b), the seat cushion 1 is deformed by the impact of the side surface of the vehicle body to deform the floor.
The left front end of 3 descends by h 1 (shown in FIG. 16) and the left rear end rises by (h 2 + h 3 ) (shown in FIG. 16). Therefore,
The shock absorber 11a attached to the side portion of the seat back on the side door 15 side is inclined forward. As a result, when the shock absorber 11a moves between the occupant 16 and the side door 15 and a side collision of the automobile occurs, the occupant 16 does not directly hit the side door 15 but is received by the shock absorber 11a. The shock absorber 11a protects the occupant 16 from the shock force by absorbing the shock force generated from time to time. In the first to fifth embodiments, the case where the side door is provided on the left side of the seat has been described. However, the present invention is not limited to this, and when the side door is provided on the right side of the seat, the shock absorption of the vehicle seat according to the present invention is also possible. The same can be accommodated by providing the device on the right side of the seat.

According to the first aspect of the present invention, the impact absorbing body forming a part of the seat back is provided on the door side portion of the seat back. Then, when the door collides with the side surface of the vehicle and the door or the floor is deformed, the moving means is actuated in accordance with the deformation to move the shock absorber between the occupant of the seat back and the door. As a result, the impact applied to the occupant is absorbed by the impact absorber.

にもならない。Therefore, it is not necessary to mount a shock absorbing material in the door or to make the door have a shock absorbing structure as in the prior art, and by combining with the shock absorbing device for a vehicle seat according to the present invention, less shock absorbing material is required. Since it is possible to provide a simple shock absorbing structure, it is possible to provide a shock absorbing device that secures a room to a desired size without increasing the vehicle width. Further, since the shock absorber is normally arranged behind the occupant, the shock absorber does not hinder the occupant and does not hinder the visibility.

【００３９】請求項２は、衝撃吸収体を平行移動させて
前方に配置するように支持したので、衝撃緩衝体を確実
にドアと乗員の間に配置することができる。According to the second aspect of the invention, the shock absorber is supported so as to be moved in parallel and to be arranged forward, so that the shock absorber can be reliably arranged between the door and the occupant.

【００４０】請求項３は、衝撃吸収体を揺動させて前方

に取付けることができる。Since the shock absorber is moved forward by tilting the entire vehicle seat forward, it is not necessary to movably support the shock absorber on the seat back. Therefore, since the shock absorber can be fixed to the seat back, the shock absorber can be firmly attached to the seat back.
