PCT No. PCT/EP91/01401 Sec. 371 Date Mar. 1, 1993 Sec. 102(e) Date Mar. 1, 1993 PCT Filed Jul. 26, 1991 PCT Pub. No. WO92/06861 PCT Pub. Date Apr. 30, 1992.A safety device in a motor vehicle including a lifting mechanism for raising a front or leading edge section of a seat cushion of a motor vehicle seat assembly. The vehicle seat assembly is supported on a set of longitudinally disposed seat rails attached to the interior floorboard of the vehicle. The seat assembly is adjustable forwardly or rearwardly in a lengthwise direction along the seat rails. The seat assembly is locked at selected positions along the seat rails by a catch mechanism. A bracket is attached to the seat rails and is connected to the lifting mechanism via a motion transmitting element or control cable device. The lifting mechanism is mounted onto the front edge section which is pivotally attached to the seat cushion. The catch mechanism includes a load-dependent breaking element which fails during a significant frontal impact to the vehicle thereby releasing the seat assembly to move in the lengthwise direction. The motion of the seat relative to the vehicle body actuates the lifting mechanism and elevates the front edge section of the seat cushion. As the edge section lifts, the supporting action of the seat cushion is improved and an occupant sitting thereon is prevented from sliding off or submarining the seat into the dashboard and/or steering column. |
