Adjustment lever, particularly for automotive HVAC applications, with clearance recovery

摘要

An adjustment device (1), comprising a support (3) through which a through bore (5) is formed; a shaft (11) mounted through the through bore and having a shoulder portion (17) suitable to axially engage the support; and a handgrip (19) snap-fitted on the shaft in such a way as to axially lock the shaft relative to the support, by co-operating with the shoulder portion. A collar (31) concentric with the bore and having a conical surface (33) on the free end thereof is disposed on the support. A plurality of elastically deformable elements (191) is disposed on the handgrip, which are arranged circumferentially along said handgrip, wherein each of the elastically deformable elements is adapted to engage the conical surface in such a way as to produce a reaction force acting on the handgrip, this reaction force having an axial component directed away from the support and a centripetal radial component.
