  • Publication number: 20070152490
    Abstract: A seat assembly for an automobile includes a support unit for supporting an overloaded seat cushion frame to prevent an overload applied to the seat cushion frame from being entirely applied to a passenger sensor to thereby prevent the passenger sensor from being damaged or deformed. The support unit comprises a stopper for limiting a downward movement of the seat cushion frame by longer than a certain distance and a stopper hooking part integrally formed at the seat cushion frame and caught by the stopper when the seat cushion frame is downwardly moved by longer than the certain distance. Thus, the structure is simple and the cost can be reduced.
