Abstract
In an activation device for a vehicle seat adjuster, particularly a motor vehicle seat, possessing a pivotable hand lever (12) for manual activation, which is supported eccentrically and working in conjunction with the adjuster (7), an acceleration-sensitive feature (24) is provided to immobilize and/or lock the hand lever (12) in the event of a crash.
Claims21
An activation device for an adjuster of a vehicle seat, with the activation device being responsive to a crash of a vehicle carrying the activation device, the activation device comprising:
- a hand lever eccentrically mounted for pivoting in response to manual activation of the hand lever, wherein the pivoting of the hand lever is operative to unlock the adjuster and thereby enable operation of the unlocked adjuster;
- and
- an acceleration-sensitive device operative for becoming activated in response to the crash, so as to restrict the pivoting of the hand lever in response to the crash, whereby the unlocking of the adjuster is prevented in response to the crash.
An activation device for an adjuster of a vehicle seat, with the activation device being responsive to a crash of a vehicle carrying the activation device, the activation device comprising:
- a hand lever eccentrically mounted for pivoting in response to manual activation of the hand lever, wherein the pivoting of the hand lever is operative to unlock the adjuster and thereby enable operation of the unlocked adjuster;
- and
- an acceleration-sensitive pendulum that is eccentrically mounted to the hand lever for pivoting relative to the hand lever from a first predetermined position into a second predetermined position in response to the crash, wherein the pendulum is operative for:
- allowing the pivoting of the hand lever, so as to allow the unlocking of the adjuster, while the pendulum is in the first predetermined position, and
- preventing the unlocking of the adjuster, by restricting the pivoting of the hand lever, while the pendulum is in the second predetermined position.
