Abstract:
A structural unit comprised of a securing element and a wiper device, in which the wiper device is detachably fastened to the securing element, wherein the detachable connection is embodied as a detent connection, wherein the detent connection (14) is embodied on the securing element (11) and elastically engages in a detent fashion in a detent seat (13) on a wiper bearing (15) of the wiper device (10), wherein the detent seat (13) is a circumferential groove (16), wherein said circumferential groove (16) describes a circle that is closed in a longitudinal direction, said detent connection (14) having at least one elastically mobile spring element (17), wherein said at least one spring element (17) has at least one detent edge (19) that is geometrically fitted to the circumferential groove (16), wherein the securing element (11) is a securing plate and the at least one spring element (17) is comprised of two elastically mobile opposing sheet metal parts (18) of the securing plate, wherein said at least one detent edge of said sheet metal parts (18) are substantially oriented toward each other in a detent position, wherein in said detent position of the two elastically mobile opposing sheet metal parts (18), respective end surfaces of the at least one detent edge (19) contact a bottom surface of the circumferential groove (16) and completely encompass the circumferential groove (16), and wherein at least one parameter selected from the group consisting of a depth of said circumferential groove (16), a wall thickness of said sheet metal parts, a length of said sheet metal parts, and a form of said sheet metal parts is selected to adjust an outward pressing force that must be exerted to release the detent connection (14) and thereby the wiper device with possible plastic deformation of an element selected from the group consisting of said sheet metal parts, said circumferential groove and both said metal parts and said circumferential groove, such that a safety requirement is fulfilled that said wiper device be sufficiently flexible and/or released in the event of a collision when colliding with a human body.
