A sliding and supporting element (2) is displaced axially in a closed tube which is provided with a slot (1a). The bolt (7) is designed as a supporting and guiding arm of a guide element. It makes the, for example, slide-mounted or ball-mounted connection with the element (2). An effective sealing of the slot (1a) of the entire length of the guide tube (1) takes place by means of two mutually overlapping elastic ice-repelling sealing strips (3). Leaks can occur in the region of the overlaps of the sealing strips (3) and are prevented by the shaping of the sliding piece (4). The sealing strips (3) and the sliding piece (4) are made of water-repelling plastic. The perfect sealing of the sliding and supporting element (2) during axial movements is afforded by the sliding piece (4). This is provided with two three-dimensional surfaces offset in their plane part by the amount of the strip thickness (8). These plane parts of the surfaces (5 and 6) extend eccentrically relative to the axis of the supporting arm (7) and thereby allow the predetermined position of the sealing strips (3) during the axial movement of the element (2). <IMAGE> |
