Abstract: A vehicular arm has a fixed axle, an arm-rest body pivotable on the axle about its axis between a raised position and a lowered position, an abutment axially fixed on the axle and rotationally coupled to the arm-rest body, and a pusher rotationally fixed and axially shiftable on the axle. The abutment lies between the pusher and the arm-rest body. Coupling projections on the pusher and on the abutment extend toward each other and have mutually engaging faces lying in planes extending at an acute angle to the axis. A spring presses the pusher axially toward the abutment, such that, when the arm-rest body is pressed toward the lowered position with a force exceeding a predetermined limit, the faces cam the pusher axially away from the abutment and permit limited rotation of the abutment and arm-rest body on the axle.

Abstract: A vehicular arm rest has a fixed axle carrying primary and secondary parts formed with meshing arrays of sawteeth angled to inhibit movement of the arm-rest body in a downward direction between a raised position and the lowered position but permit movement of the arm-rest body in the upward direction between the lowered position to the raised position. A spring braced between an abutment and the secondary part urging the secondary-part teeth into mesh with the primary-part teeth. Cam formations push the secondary part away from the primary part on pivoting of the primary part in the downward direction from the raised position of the arm-rest body toward the lowered position for decoupling the primary-part teeth from the secondary-part teeth and couple the primary-part teeth with the secondary-part teeth and prevent further movement in the downward direction on reaching the lowered position.

Abstract: The invention relates to an armrest, such as a middle armrest, comprising an armrest body (17) which may be pivoted about a horizontal axis (12), between an upright and a lowered position, provided with a ratchet lock (P, S), only operating on a downwards pivoting movement (N), which comprises a primary section (P), arranged to rotate about the axis (12) in connection with the armrest body (17), with a secondary piece (S), mounted such as to be stationary, at least relative to the axis (12), cooperating therewith. The ratchet lock (P, S) separates the primary piece (P) and the secondary piece (S) from each other in the upright position and on beginning an upwards pivoting movement (N), by means of a control device (R) and returns the above to engagement in a lowered position. The primary piece (P) and the secondary piece (S) form facing planes of ratchet teeth (Z1, Z2), which are coaxial to the axis (12). The secondary piece (S) may be axially displaced.

Abstract: The invention relates to an armrest, such as a middle armrest, comprising an armrest body (17) which may be pivoted about a horizontal axis (12) between an upright and a lowered position, provided with an overload protection (W, D, T, E), which, when the armrest body (17) is in the lowered position, releases the armrest body (17) on an overload occurring and permits a down-ward pivoting of the armrest body (17). An abutting piece (W) mounted to rotate about the axis (12) has one side thereof connected to the armrest body (17) with a rotating connection and is axially fixed on the axis (12) in order to form the overload protection (W, D, T, E). On the other side of the abutting piece (W), a pressure piece (D), moving axially, but not rotating on the axis (12), is supported by a return force of a spring element (T).
