The invention relates to guiding sliding seats, e.g. sliding motor vehicle seats, and wants to make a seat guide available that is subject to little friction.

For motor vehicles, low-friction seat guides are already known that allow the setting of the Allow seat in the longitudinal direction of the vehicle and those between those connected to the seat Part and the part connected to the floor or a carrier roller bearing body provided are.

The aim of the invention is to change the guide equipped with roller bearing bodies to that effect to perfect that regardless of manufacturing inaccuracies and regardless of Wear the parts of the guide are held together positively and there is play between them Sharing is automatically compensated.

This aim is achieved according to the invention in that the roller bearing bodies are helical springs are whose longitudinal axes run transversely to the direction of displacement of the part connected to the seat and to which holding elements for securing the transverse position are assigned. The coil springs do not work only as the friction-reducing rolling elements, but at the same time form resilient supports, which the Ensure frictional cohesion of the guide parts and any play between them Balance sharing. The easy movement of the guide is made by the movement of the seat alternating compression and expansion of the coil springs and the resulting Deformation work not affected.

The seat guide according to the invention can be implemented in many ways. Some embodiments and other features are illustrated in the drawings and are intended below explained. In the drawing shows

F i g. 8 is a sectional view along line 8-8 of FIG. 7,

FIG. 9 shows a sectional view corresponding to FIG. 2 of a further embodiment according to FIG

as invention,

Fig. 10 is a partial side view of an additional Embodiment according to the invention, wherein a different design of the bearing member is used finds

11 is a partial sectional view along line 11-11 of FIG. 10,

12 shows a further embodiment of the bearing member in side view.

As can be seen from the side view according to FIG. 1, the seat 10 is on the vehicle floor 11 in FIG Arranged movably in the longitudinal direction by means of a device consisting of a on the vehicle floor 11 fixed part 12 and a part 13 which is attached to the underside of the seat 10 is and with the part 12 forms a telescopically displaceable guide. The movability of the part 13 opposite the part 12 is made possible by roller bearing bodies in the form of helical springs 14, which are spaced from each other in the longitudinal direction.

According to FIG. 2, the part 12 consists of an upper part extending in the longitudinal direction of the vehicle Tube 15, the axis of which is slightly bent upwards, and one designed as a double flange Web 16 with sideways facing flanges 17, which by means of screws 18 on the vehicle floor are set. The part 13 is also tubular and designed so that it the tube 15 of the

Way to set the seat in the new setting. As the F i g. 3, 4 and 5 show that there is a greater longitudinal displacement of the seat allow each roller bearing body 14 from a holding member 21, 5, the seat guide according to FIG. 7 which is made of wire and on which multiple and 8 are used. This tour consists of Coil springs 22 are pushed. The retaining part 40, which is placed on the underside of the seat organ 21 is ring-shaped; its ends 23 can be fastened radially, a tubular on the outward and run along the web 16 part 41 attached to the vehicle floor and an interposed part 41 a rotary movement of the holding member is established in the tube 42. The parts 40, 41 and 42 21 prevented. Each coil spring 22 consists of are provided with corresponding surfaces; between a plurality of tight and tightly wound winches see the part 40 and the tube 42 are screw connections of the same diameter. As FIG. 5 shows, springs 43; further coil springs 44 are between the springs 22 have seen the tube 42 and the tubular part 41 in the unstressed state stretched form, d. that is, its axis is straight.

The roller bearing body arranged between the surfaces 19 and 20. In this case, a wire bracket 48, which in the Movement of the bearing body with respect to the general has the same shape as the part 13 and the tube 15 of the part 12 to delimit the speaking surfaces of the parts 45 and 46. are stops distributed in the direction of displacement. A modified form of the holding element is shown in 25 in the form of impressions on the part 13 in front of FIGS. 10 and 11. After that there is seen, which with the roller bearing bodies 14 in 25, the holding member 50 from a curved to form a ring engagement come. Additional stops in the form of a metal plate, the ends 51 of which are impressed from one another 26 are standing on the tube 15 of the part 12 so that they are in front of the web 16 of the part 12 appropriate. In addition, the ends of the ended. The holding member 50 is provided with a slot 52 Tube 15 is equipped with lateral projections 27, which over almost its entire length tet, which reaches a separation 30 when adjusting the seat and ends just before the ends 51. The Schrauder Rolling bearing body 14 from the part 12 is impossible to benfedern 53 are inserted into the slots 52, do. Another embodiment of the holding member is illustrated when the seat is adjusted, the screws roll at 55 in FIG. 12; execution benfedern 22 of the roller bearing body 14 on the surface is similar to that of FIGS.
