The present invention relates to a self-adjusting stopper for dampening movable parts, in particular for lids, hoods or the like in automotive vehicles, and comprises a stop element, a casing, a clamping element and a coupling element in cooperative relationship. Initially the stop element projects a maximum distance out of the casing. By closing the part which has to be dampened, for example the hood of an automotive vehicle, the stop element becomes displaced into the casing. After opening the lid, the clamping element is locked to the stop element by rotating the coupling element to axially adjust the stop element within the casing. A further adjustment is not required. According to the invention, the stop element will be automatically adjusted in a proper axial position by just closing and opening the lid.

Self-adjusting stop means for cushioning

A guiding sleeve for the headrests in seats of vehicles which slidably receives a rod of the headrest comprising at least one snap-in stop, the sleeve bore at the upper end including an extension for receiving a spring element which with a first portion cooperates with said headrest rod and with a second portion is supported by the wall of the extension. An unlocking element with two parallel spaced legs are arranged in the extension, which legs, being located at the side of the sleeve bore, with their ends cooperate with the first portion of the spring element and are movable from a gripping position engaging the spring element towards their longitudinal extension which causes the first spring portion to drop out of engagement with the rod. The spring spring comprises a pair of spring legs connected to a cross arm which spring legs engage the rod at the side, the cross arm being supported by the wall of the extension, and the unlocking element between the legs comprising a cam surface cooperating with the ends of the spring legs so that the spring legs are bent away from the rod when moving the grip into the extension.
