Patent number: 6902234Abstract: The motor vehicle seat of a motor vehicle comprises an underframe and a seat carrier that is height-adjustably connected to the underframe through rear oscillating cranks. A catch device is directly assigned to one of the two rear oscillating cranks. A non-rotatable tie bar joins the two rear oscillating cranks so that they are parallel when the vehicle seat is subjected to normal load. A retaining device has a sector gear firmly connected to the other one of the two rear oscillating cranks. An engaging piece which is movably disposed on the seat carrier or on the underframe, is provided with teeth devised for engagement with the sector gear and is disengaged from the sector gear as long as the vehicle seat is subjected to normal load. When the associated motor vehicle is subjected to a crash load an actuator is activated and causes the engaging piece to move into positive mesh with the sector gear.Type: GrantFiled: January 30, 2003Date of Patent: June 7, 2005Assignee: C.
