An upper-front of a seatback is cut, providing a hole at a position the occupant's shoulder may lie, and an engaging means able to engage with a shoulder webbing is fitted in the hole. The engaging means holds the shoulder webbing, which is wrapped around the occupant. The engaging means is, for example, a (second) buckle fitted in the hole. A second tongue (intermediate tongue) is mounted on a middle part of the shoulder webbing. The shoulder webbing is wrapped slantwise around the occupant's shoulder when the second tongue is engaged with the second buckle.

Seat belt device for the vehicle seat

A passenger protection device includes an airbag case to be provided in an arm rest of a vehicle seat, and an airbag; wherein the airbag case has a passenger-side wall that is a cover that can rotate upward around its upper end; the device comprises support members that lie flat on a passenger-side surface of the cover and can assume an upright orientation; and if the vehicle collides at one side, the airbag is inflated and deployed outside the airbag case through the opening made in a passenger-side of the arm rest and pushes the cover, thereby rotating the cover upward, the support members may stand on the airbag case, supporting the cover rotated upward from back in an upright orientation.

Passenger protection device

A seat cushion is arranged on a riser. A strut is coupled, at lower end, to the rear end of the riser, and is provided at the back of the seat cushion. The seatback is secured to the strut, and is isolated from the seat cushion. The seatback and the seat cushion can therefore move, independent of each other. The seatback or the seat cushion, or both are lifted or lowered by a lifting/lowering means. Thus, the seatback and the seat cushion are lifted or lowered relative to each other. The lower half of the seatback, which supports the hips and lower ribs in the main, is made narrow than the upper half that supports the shoulder blades in the main. The seat cushion has, in the middle part of the rear end, a U-notch which loosely holds the narrow lower half.

Seat

The seatback has a seat surface curving and gradually bulging in the up-down direction, along the occupant's shoulder blades, and curving in the left-right direction and receding to support the occupant's ribs. Preferably, the seat surface of the seatback extends upward to support the lower part of the occupant's neck, thus supporting the same in the up-down direction, and recedes to support the occupant's shoulder blades in the left-right direction.
