A battery packaging material has a very thin aluminum alloy foil with a thickness of not more than 40 &#x3bc;m, in which pinholes or cracks are unlikely to occur during molding, which has excellent moldability and appearance after molding, which is unlikely to be erroneously determined to be a defective product, and which makes highly accurate defect determination possible. The battery packaging material includes a stacked member provided with at least, in this order: a base material layer; an aluminum alloy foil layer; and a heat sealable resin layer, wherein: the aluminum alloy foil layer has a thickness of not more than 40 &#x3bc;m; the aluminum alloy foil layer is an aluminum alloy conforming to JIS standard A8021; and the aluminum alloy has a maximum crystal grain size of not more than 25 &#x3bc;m, and an average crystal grain size of not more than 10 &#x3bc;m.

A seat cushion of vehicle seat including a seat cushion frame and a bottom panel member on which a foam padding is mounted. The bottom panel member has a thigh support area fixed to a forward portion of the seat cushion frame and a buttocks support area situated in a rearward portion of the seat cushion frame. The buttocks support area has a resiliently deformable area in which are formed beads, each being resiliently stretchable laterally relative to the central line thereof by a downward load applied to the buttocks support area, whereby the resiliently deformable area is rendered deformable and displaceable downwardly. The buttocks support area may be made narrow by forming two inwardly curved edge portions in the respective sides thereof to thereby allow that buttocks support area to be warped downwardly. Hence, the buttocks support area is resiliently displaceable vertically relative to the seat cushion frame.

Seat cushion of vehicle seat

A seat back of vehicle seat, on which a headrest unmovable in fore-and-aft direction is mounted, is constructed such that a resilient support member for supporting a back portion of seat occupant is provided therein, and the upper region of that resilient support member is operatively connected, via movable connecting element, with a biasing element. When a rear-end collision occurs, the resilient support member is displaced far backwardly by excessive great load applied thereto from the seat occupant, overcoming a biasing force of the biasing element, thereby causing the biasing element to stretch long, so that the resilient support member with the seat occupant's back portion thereon is displaced backwardly and upwardly under guidance of the movable connecting element so as to quickly bring a head of the seat occupant to a point close to the headrest, prior to the head being directly pressed against the headrest.

Structure of seat back with headrest

A shoulder receiving portion is defined in each of two lateral frame members of seat back framework of vehicle seat in order to receive two shoulder portions of seat occupant in the case of rear-end collision, prior to a seat occupant's back portion being moved close to an upper frame member of the seat back framework. The shoulder receiving portion is therefore arranged in an upper region of each of the two lateral frame members so as to project forwardly from a plane where the two lateral frame members lie, and the upper frame member is formed in substantially 'inverted-U' shape and inclined backwardly distant from the two lateral frame members, This arrangement avoids unpleasant pressed touch to be given to the seat occupant's back portion in the case of rear-end collision and may prevent a great impact from being imparted to vertebrae of the seat occupant.

Seat back framework

In an upper frame member of seat back framework, an upward-slippage prevention portion is simply defined to prevent a seat occupant's back portion from being slipped or dislocated on and along a seat back in the case of rear-end collision. The upward-slippage prevention portion has a sloped region for receiving the seat occupant's back portion which is to be slipped or dislocated on and along the seat back under inertia when a rear-end collision occurs and thereby preventing an undesired upward slippage or dislocation of that seat occupant's back portion which will result in damage of his or her neck or cervical vertebrae.

A vehicle seat, including two links movable for adjustment in height of the seat, is provided with a reinforcing transmission shaft. The reinforcing transmission shaft is rotatably connected between two frame members of seat cushion frame in the seat, while extending through the two links. Further, two pinions are fixed on the respective two end portions of the reinforcing transmission shaft and respectively meshed with two gear portions defined in the respective two links. With such arrangement, in the case of rear-end collision, most of great load applied to the links is transmitted, via the reinforcing transmission shaft, pinions and gear portions, to each of the two frame members, thereby preventing deformation of one of the two links to avoid lowering of the seat or inclination of one side of the seat as found in a rear-end collision case.

Vehicle seat

Vehicle seat including a link for raising and lowering the seat and a tilt pan disposed forwardly of seat cushion frame of the seat. Rotatably provided to the seat cushion frame is an actuator link having: one end portion pivoted to the tilt pan; and another end portion formed with sector gear portion and arcuate hole. A pin for supporting a gear case having a pinion meshed with the sector gear portion is fixed to the seat cushion frame. Such pin is used with both of the link and actuator link, in common. Namely, an upper end portion of the link and the afore-said another end portion of actuator link are collectively disposed at that pin so as to overlap each other, and the upper end portion of link is pivotally connected to the pin, whereas the pin passes through the arcuate hole of actuator link.

A structure for supporting a generally U-shaped unlocking lever in seat slide device, wherein a main support portion of a generally channel cross-section is provided at each of a pair of the seat slide devices so as to support each of the two lateral portions of the unlocking lever. Formed respectively in the upper and lower walls of that main support portion are downwardly and upwardly curved protrudent portions, so that the two lateral portions of the unlocking lever each extends between those downwardly and upwardly curved protrudent portions. This arrangement gives a play to the two lateral portions of unlocking lever. Namely, both two free end portions respective of such two lateral portions are inclinable vertically relative to a support point between the afore-said two curved protrudent portions, while the two lateral portions themselves are also slidable therebetween in transverse direction of the seat slide device, thereby absorbing differences in size and shape which may occur in each of unlocking levers to be used.
