Key having a retractable insert and corresponding deployment module

摘要

The present invention relates to a key (1), in particular for a motor vehicle, comprising: —a housing (3), —an insert (5, 7) mounted pivotally about a pivoting axis (A) and comprising a key-bit support (5) and a key bit (7), —a mechanism for deploying the insert (5, 7) mounted in said housing (3) and comprising: • a push button (19) axially received in a housing (21), and • an elastic return element (23) for the insert (5, 7), wherein a first end (23a) is connected to the insert (5, 7) at the support (5), said support (5) or said button (19) comprising two retaining lugs (39) ascending parallel to the pivoting axis (A) and positioned facing each other and symmetric relative to said pivoting axis (A), said retaining lugs (39) defining, on each side of the pivoting axis (A), a space (50) for the angular displacement of the first end (23a) or of the second end (23b) according to an angle of between 10° and 90°.

主权项

1. A key for a motor vehicle, comprising:
a casing having an upper half-shell that forms a cover and a lower half-shell that forms a casing bottom; an insert mounted in a pivotable manner about a pivot axis and comprising a key-bit support and a key bit secured to the support; an insert deployment mechanism mounted in said casing and comprising:
a push button housed axially in an associated housing of the upper half-shell and protruding from this upper half-shell in order to be actuated by a user, andan elastic return element comprising: a first end that is connected to the insert at the support via two parallel lips at the bottom of the push button, for urging said insert into a pivoting movement toward a use position when the push button is actuated, and a second end positioned between two holding pegs of the support which define, on either side of the pivot axis, a space for angular travel of the second end of the elastic return element at an angle of between 10° and 90°,wherein the space for angular travel between the two holding pegs holding the second end of the elastic return element is larger than a space between the two parallel lips in the push button which house the first end of the elastic return element, so as to facilitate the insertion of the second end into the space between the two holding pegs after insertion of the first end into the parallel lips.
