Abstract
The invention is based on a wiper installation, having at least one wiper bearing (10), in whose hearing housing (12,126) a wiper shaft (18) is supported and axial fixed, and which on its end (20) protruding from a vehicle body (24) carries a wiper arm (60). The wiper shaft (18) is displaceable into the vehicle body (24) when an axial force (40) that exceeds a predetermined magnitude is exerted from outside on the end (20).
Claims11
A wiper installation, comprising:
- at least one wiper bearing (10) having a bearing housing (12, 126), wherein a wiper shaft (18) having opposite ends is supported and axially fixed in said bearing housing, wherein one of said ends (20) of said wiper shaft protrudes from a vehicle body (24) and carries a wiper arm (60), wherein the wiper shaft (18) is displaceable into the vehicle body (24) when a critical axial force (40) that exceeds a predetermined magnitude determined by an injury risk of a person's body is exerted from outside on the one of said ends (20), wherein means (56, 88, 116, 120, 122, 128, 132) that are plastically deformable in an axial direction are provided at a location selected from the group consisting of between an inward-acting stop (54, 58, 84) of the wiper shaft (18) and the vehicle body (24) and between said inward-acting stop and a part (12, 130) solidly connected to said vehicle body (24), wherein the means are a plastically deformable sheet-metal sheath (56), wherein the sheet-metal sheath 56 has an axially corrugated region (90).
