Estimating the term…
A device for restoring a rotary member into a defined normal position, with a spatially stationary fixed catch, which predetermines the normal position, and a driver catch, which is coupled to the rotary member and can be moved past the fixed catch, each of which has stop surfaces embodied on each of its opposing sides, and with a clamping spring, which encompasses the catches in a prestressed fashion with two bent spring legs, in order to prevent a rotary play between the clamping spring and the catches in the normal position, and an elastic spring element in at least one leg section of the spring legs extending across the stop surfaces of the catches, which spring element is supported against the associated stop surface with a spring force that is less powerful than the prestressing force of the clamping spring.
A device for restoring a rotary member into a defined normal position, comprising
The device according to claim 2, wherein the cross section of the spring wire of the clamping spring (18) is reduced in the vicinity of the spring leg (181 or 182) in order to produce a spring elasticity of the spring leg (181 or 182).
The device according to claim 2, wherein the spring leg is embodied as being of sufficient length to produce a spring elasticity of the spring leg (181 or 182).
The device according to claim 2, wherein the stop surfaces (131, 141 and 132, 142) of the catches (13, 14) engaged by the spring leg (181 or 182) are spaced radially far enough apart from each other that the spring leg (181 or 182) is able to flex between its contact regions against the stop surfaces (131, 141 and 132, 142).
The device according claim 2, the at least one spring leg (181, 182) tapers toward its leg end.
The device according to claim 2, further comprising an additional elastic spring element at the leg end of at least one spring leg (181) embodied as a flexible tongue (19′) that is bent in one piece from the spring leg (181) and rests in a prestressed fashion against a stop surface (141).
