Seat cushion restraint system

摘要

A seat structure has a device which acts to reduce the interaction between the lower extremities of a vehicle occupant and the vehicle interior. The seat structure also reduces the interaction between the vehicle occupant's legs and the instrument panel by limiting the forward travel of the lower torso. The seat structure may employ an airbag, a mechanical device or a pyrotechnic device, which elevates only the front part of the seat cushion to remove the leg and foot from the path of the intruding or reactive structure, and to minimize the travel of the lower torso into the instrument panel. A crash sensor activates the device when the crash sensor senses a crash of a selected severity.
