で、乗員の頭部を保護するものである。The structure disclosed in the above-mentioned Japanese Patent Application Laid-Open No. HEI 10-19619 has a structure in which a headrest is moved forward to support a head, so that a rotation center support mechanism and a plate are provided. There is a problem that the structure is complicated. In addition, the aforementioned patent 2862
No. 853 further includes an impact receiving plate for operating a link mechanism for rotating the headrest, so that the number of parts increases and the structure becomes complicated. In addition, although the impact receiving plate has a low rigidity portion formed at the lower portion, there is a concern that the rigidity may vary and may not operate correctly. That is, if the plate is not broken, the deformation load is unknown, and the plate with the determined deformation load cannot be used. The present invention protects an occupant's head with a simple configuration.

る。In this case, the outer periphery of the back cushion member 12 located on the front side of the spring 7 is covered with a skin member 20.
A side skin member 22 that covers the side cushion member 14 and an upper skin member 23 that covers the upper cushion member 16 are connected around the center skin member 21 of the center cushion member 13. Since the slack portion 24 is formed by loosening in consideration of the backward movement amount, when the central cushion material 13 moves backward, the slack portion 24 extends around the central skin member 21 of the skin member 20 and the central cushion material 13 is smoothly moved without hindrance to the backward movement.

５は、所定以上の衝撃荷重が係ると、必ず後方移動し、
作動は確実である。Therefore, since the central support portion 5 moves rearward as a whole, the headrest 4 reliably supports the head and neck of the occupant, thereby preventing the occurrence of whiplash. In other words, when the deformation predicted by the variation of the deformation mode when the impact load is applied is not performed even when the low rigidity portion is provided on the frame, the rearward movement of the central support portion 5 is not reliable, but the central support portion 5 The normal seating load is supported by the spring 7, but when an impact load exceeding a predetermined level is applied, the headrest 4 is allowed to move backward with respect to the headrest 4, so that the elasticity of the spring 7 is measured at the time of assembly. Then, the working load moving backward of the central support portion 5 can be reliably predicted,
Can be set as desired. Therefore, the central support portion 5 always moves backward when an impact load exceeding a predetermined value is applied,
Operation is assured.

Therefore, a vehicle that meets various conditions such as the size of the vehicle seat 1 and the physique of a seated person. Sheet 1 can be provided. In addition, since it is only necessary to replace the spring 7 to deal with a seated person, there is no need to prepare various frames before assembling, and it is also possible to change after assembling, facilitating manufacture and assembling, and managing inventory. Including, lower overall costs.

持構成を変更する必要はなく、簡単な構成にできる。In this case, since the center cushion member 13 moves backward with respect to the fixed-side cushion member 17, the occurrence of whiplash can be prevented with a small movement. The center support portion 5 connects the upper portions of the left and right side cushion members 14 with an upper cushion member 16, and forms a fixed cushion member 17 by the side cushion members 14 and the upper cushion member 16. Since the central cushion member 13 may be formed separately from the support member 17, there is no need to change the support configuration of the headrest 4, and a simple configuration can be achieved.

い。Thus, the outer periphery of the backrest cushion member 12 is covered with the skin member 20, and the periphery of the center skin member 21 of the center cushion member 13 is covered with the side skin member 22 covering the side cushion member 14. The upper skin member 23 that covers the upper cushion material 16 is connected, and the connection portion is loosened in consideration of the backward movement amount of the central cushion material 13 to form the slack portion 24. At this time, the slack portion 24 extends and does not become an obstacle at all.

しながら耐久性を向上させる。The slack portion 24 is provided at the center cushion material 13.
Since it is inserted into the insertion groove 26 formed between the surroundings and the fixed-side cushion material 17, the slack portion 24 can be formed sufficiently long, and the appearance does not change at all from a normal seat, and the appearance does not deteriorate. . So, as mentioned above,
Since the center support 5 only moves backward against the elasticity of the spring 7, the center support 5 moved backward by the load is
When the impact load is eliminated, the spring 7 returns to its original position due to its elasticity. Therefore, the skeletal frame 10 does not deform when subjected to an impact load.
The initial strength can be easily maintained, and as a result, the durability is improved while maintaining the initial state.

ら、弛み部２４を充分に取ることができる。According to the present invention, left and right springs 7 are juxtaposed at predetermined vertical intervals on a side frame portion 11 of a skeletal frame 10 capable of mounting and supporting a headrest 4, and a backrest cushion is provided on the front side of the springs 7. The backrest cushion material 12 is provided.
The backrest sheet has an outer periphery covered with a skin member 20. The backrest sheet includes a central support surface 5 for supporting the back or shoulders of the occupant, and side support surfaces 6 on both left and right sides of the central support surface 5. And the backrest cushion material 12 is
A center cushion member 13 corresponding to the center support portion 5 is replaced with a side cushion member 14 corresponding to the left and right side support surfaces 6.
And the skin member 20 connects the side skin members 22 covering the left and right side cushion members 14 to the periphery of the center skin member 21 of the center cushion member 13, and the connection portion is formed by the central cushion member 13. The slack portion 2 is formed in the slack portion 24 which is slackened in consideration of the backward movement amount of the material 13.
4 is the periphery of the central cushion 13 and the side cushion 1
The spring 7 supports a normal seating load but allows a rearward movement of the central support portion 5 with respect to the headrest 4 when an impact load exceeding a predetermined level is applied. Since the vehicle seat is configured as described above, only the elasticity of the spring 7 is set with respect to the impact load, so that the working load of the central support portion 5 moving backward can be predicted with certainty, and the rearward movement can always be performed. However, the operation is assured, and the combination of the spring and the cushioning material can provide good cushioning properties. Since the cushioning material is merely divided, the headrest 4 is fixed to the fixed frame 1.
3, the headrest 4 can be used in common with the normal seat, and the cost can be reduced. According to the present invention, the center support portion 5 includes a center cushion member 13 and a fixed side cushion member 17 in which upper portions of left and right side cushion members 14 are connected by an upper cushion member 16.
And the slack portion 24 is provided at the center cushion material 1.
Since the vehicle seat is inserted into the insertion groove 26 formed between the periphery of the base 3 and the fixed-side cushion member 17, the slack portion 24 can be sufficiently removed.
