Abstract

Disclosed is a vehicle seat with suspension device in which there is fixed a belt anchor to be jointed with a seat belt and the suspension device is adapted for absorbing a vibration or shock. In such seat, there are a pair of protection plates arranged such that they are respectively fixed on the rearward portions of the upper and lower frames of the suspension device and are disposed in a vertically mutually meeting relationship. Each of the protection plates are at its end portion formed with a curved or bent engagement terminal portion so arranged that both engagement terminal portions of both protection plates are in a halfway engagement with each other, with a predetermined distance present between their extremities and innermost curved portions. This arrangement allows a pulling force exerted on the belt anchor to be transmitted through the protection plates to the vehicle floor and received by the same.

Claims

1. A vehicle seat with a suspension device in which there is fixed a belt anchor to be joined with a seat and the seat is supported by the suspension device and in which the suspension devise includes an upper frame and a lower frame, characterized in that there are provided a pair of protection plates so arranged that one of them is fixed on a rearward portion of said upper frame and the other of them is fixed on a rearward portion of said lower frame in such a manner that they are disposed in a vertically mutually meeting relationship, in that each free end portion of said protection plates is formed with a curved or bent engagement terminal portion disposed between said upper and lower frames, such that both said engagement terminal portions of said protection plates are faced toward each other, and in that each of said engagement terminal portions comprise an innermost portion in an extremity, whereby said protection plates are in a halfway engagement with each other, in such a way that a predetermined distance exists between said respective extremities and said respective innermost curved portion, of said engagement terminal portions and wherein said plates are fixed in a position in which they extend from one side to the other side of said frames at the rear thereof, substantially covering the entire space defined at the rear of said seat between said upper and lower frames.

2. The vehicle seat according to claim 1, wherein said suspension device comprises an upper frame fixed on a bottom side of a seat cushion of said seat, a lower frame fixed on a floor of the vehicle, and an X-shaped link provided between said upper and lower frames such that said seat cushion is movable vertically relative to said floor, and wherein on said upper frame there is fixed said belt anchor.

3. The vehicle seat according to claim 1, wherein said protection plates are formed of a rigid plate-like material and each of said protection plates is at its end portion formed with an engagement terminal portion of a U-shaped configuration, and wherein both said terminal portions are disposed in a vertically mutually meeting relationship.

4. The vehicle seat according to claim 1, wherein said protection plates are formed of a plane plate.

5. The vehicle seat according to claim 1, wherein said protection plates are formed of a rigid plate of a corrugated configuration.
