Abstract

A declutching system for handle arrangement of a motor vehicle includes: an axle whereon are arranged a housing and a declutching member. The declutching system presents two positions: a clutch position wherein the declutching member blocks the housing in rotation around the axle by cooperating with at least one cam of the housing, and a declutch position wherein the declutching member allows the housing to rotate around the axle. The declutching member includes a body to which extends at least one reversible deformable leg. In the clutched position, the at least one reversible deformable leg cooperates with the at least one cam of the housing and blocks into rotation the housing around the axle. In the declutched position, the at least one reversible deformable leg is deformed in the direction of the body and thereof enabling the rotationally displacement of the housing around the axle.

Dependent claims

A declutching system for handle arrangement of a motor vehicle, the declutching system comprising:

an axle on which a housing and a declutching member are arranged, the declutching member being completely surrounded by the housing, the declutching system presenting two positions, a clutch position, in which the declutching member blocks rotation of the housing around the axle by cooperating with at least one cam of the housing, and a declutch position, in which the declutching member allows the housing to rotate around the axle,
wherein the declutching member comprises a body from which at least one reversible deformable leg extends,
wherein in the clutched position of the declutching system, the at least one reversible deformable leg cooperates with the at least one cam of the housing and blocks the rotation of the housing around the axle, and
wherein in the declutch position of the declutching system, the at least one reversible deformable leg is deformed in a direction of the body and thereby enables the rotation of the housing around the axle.
