Forwardly movable vehicle seat comprises catch devices united by transverse bar, actuation lever connected to transverse bar, and overload spring between transverse bar and driver lever or between actuation lever handle and transverse bar

摘要

A forwardly movable vehicle seat comprises an underframe including two catch devices united by a transverse bar and an actuation lever connected to the transverse bar; and a driver mechanism connecting the seat back to the transverse bar. An overload spring between the transverse bar and the driver lever or between the actuation lever handle and the transverse bar is rigid on one side to allow sufficiently large force to be transferred for actuating the catch devices but compliant on another side to yield upon actuation of the actuation lever before the driver mechanism gets damaged. A forwardly movable vehicle seat comprises an underframe (20) including a longitudinal adjusting device comprising two pairs of rails, two catch devices (26) united by a transverse bar and an actuation lever (30) connected to the transverse bar for actuating the catch devices; a seat pan (32) that is carried by the underframe; and a seat back (34) that is pivotal about a seat back hinge (36) associated with a stop device (40) and on which there is disposed a disengagement lever (38) for unlocking the stop device when in an actuated position so that the seat back is foldable, a driver mechanism connecting the seat back to the transverse bar being provided and the catch devices being unlocked and the seat being allowed to be brought from an initial position to a forwardly moved position when the seat back is folded forward. The driver mechanism comprises a driver lever that is disposed on the transverse bar. An overload spring is rigid on one side to allow sufficiently large force to be transferred for actuating the catch devices but compliant on another side to yield upon actuation of the actuation lever before the driver mechanism gets damaged. It is disposed between the transverse bar and the driver lever or between the handle of the actuation lever and the transverse bar.
