害を確実に防止することは困難であった。2. Description of the Related Art A headrest is provided above a seat back of a vehicle seat in order to prevent an occupant from whipping when a vehicle is hit later. However, in the conventional type, as shown in FIG. 14, due to the acceleration of the entire seat due to the impact at the time of a rear-end collision and the inertia of the occupant, the seat back a is inclined rearward, and the body of the occupant is lifted obliquely rearward. The head of the occupant shifts upward of the headrest e, a large load acts on the neck, and it is difficult to reliably prevent the whiplash injury of the occupant.

防止している。In this prior art, the load from the occupant applied to the seat back a due to the movement of the upper half of the occupant's body rearward due to the impact when a rear-end collision is applied is received by the impact pressure placed in front of the seat back frame b. The headrest support frame d, which is absorbed by the rearward movement of the frame c and is coupled to the impact pressure receiving frame c, is rotated around the upper side portion b ′ of the seatback frame b along with the rearward movement, and the upper end of the headrest support frame d is The headrest e provided at the front is moved forward. In this way, the headrest e is moved forward during a rear-end collision to approach the occupant's head, and the head is prevented from shifting upward from the headrest e during a rear-end collision, thereby effectively preventing a whiplash injury. .

The springs 7a and 7b are fixed to the ends by welding, respectively. The connecting members 8a and 8b are set to have rigidity so as to extend rearward only when a load of a predetermined value or more is applied. Then, as shown in FIG. 4, when the lower connecting member 8b exerts a load larger than a predetermined value on the upper connecting member 8a via the S springs 7a and 7b, the expansion amount thereof is large. Is configured to be.

a、8bの有するバネ作用によって、衝撃エネルギーが
吸収されるため、乗員に作用する衝撃力が緩和される。When the vehicle is rear-end hit, a shocking load is applied to the seat toward the front, and the load of the occupant is applied to the S springs 7a and 7b toward the rear due to the reaction. At this time, a load of a predetermined value or more is applied to the connecting members 8a and 8b located at both ends of the S springs 7a and 7b, so that the connecting members 8a and 8b.
4 extends rearward as shown in FIGS. 4 and 5, and the entire body of the occupant does not tilt backward and moves rearward in a substantially original posture. For this reason, as shown in FIG. 14, the occupant does not float up obliquely rearward due to the impact at the time of a rear-end collision,
The head of the occupant is reliably received by the headrest 3, and the neck of the occupant is protected. Also, the connecting member 8
Since the impact energy is absorbed by the spring action of a and 8b, the impact force acting on the occupant is relaxed.

Since the load acting on a and 7b reaches about 1,000 kgf, it is preferable to set the rigidity such that the connecting members 8a and 8b extend backward only when the load reaches 800 kgf or more. During normal operation, the maximum load acting on both S springs 7a and 7b is 15
Since it is about 0 kgf, the connecting members 8a and 8b maintain their original shapes, and as a result, smooth operation can be maintained. In this embodiment, the lower connecting member 8b is the upper connecting member 8b.
The amount of extension at the time of a rear-end collision is set to be larger than that of a. This is to make it easier to keep the posture of the occupant at the rear-end collision in a more vertical state.

The headrest 3 is provided at 9a. As shown in FIG. 7, the headrest support arm 9 is composed of a pair of left and right bending arms, and the bracket portion 9b provided on the post portion 9a of the headrest support arm 9 is fitted on the upper side portion 5a of the seatback frame 5 to provide a seatback. The frame 5 is rotatably supported. The lower end of the headrest support arm 9 is connected to the end of the upper S spring 7a.

れるため、乗員に作用する衝撃力が緩和される。When the vehicle is rear-end hit, a shocking load is applied to the seat toward the front, and the load of the occupant is applied to the S springs 7a and 7b toward the rear due to the reaction. At this time, since a load greater than a predetermined value is applied to the connecting members 8a located at both ends of the upper S spring 7a, the connecting member 8a extends rearward as shown in FIGS. 8 and 9, and the body of the occupant leans backward. Prevent to some extent. Further, as the upper connecting member 8a extends rearward, the headrest support arm 9 rotates about the seat back frame upper side 5a as a rotation fulcrum P as shown by an arrow in FIG. 9, and the headrest supported on the upper end thereof. 3 moves so as to approach the occupant's head. Therefore, the situation in which the occupant floats up obliquely rearward during a rear-end collision is prevented to some extent, and the headrest 3 instantly approaches the occupant's head. Protected. Further, since the impact energy is absorbed by the spring action of the connecting member 8a, the impact force acting on the occupant is alleviated.
