Embodiment Construction

[0020] figure 1 A longitudinal adjuster 1 according to the invention is shown. It has, for example, a lower rail 2 , which is preferably fixedly arranged on the body of the vehicle. The upper guide rail 3 is arranged to be displaceable longitudinally relative to the lower guide rail. The upper rail 3 is supported on the lower rail in two contact areas 7 , 8 with respect to the cross section, wherein the upper rail is guided on the lower rail in these two contact areas. The contact regions 7 , 8 are preferably arranged to the left and to the right of the preferably U-shaped central region 9 of the cross section of the lower rail 2 . In the contact area 7 , 8 , roller parts, in this example balls 4 , are arranged between the two guide rails 2 , 3 . In order to be able to fasten the vehicle seat in the desired position in each case, the longitudinal adjuster preferably has a fastening device 5 which releasably fastens the upper rail 3 relative to the lower rail. In this exam...

Abstract

A longitudinal adjuster in the interior of a motor vehicle, has an upper and a lower rail, between which at least one rolling body is provided. A projection is provided on the upper and / or lower rail, the projection forming a local contact point between the two rails.

Description

technical field [0001] The invention relates to a longitudinal adjuster for use in the vehicle interior of a motor vehicle, having upper and lower guide rails between which at least one roller element is arranged. Furthermore, the invention also relates to a vehicle seat with a longitudinal adjuster according to the invention. Background technique [0002] Longitudinal adjusters of a general type are sufficiently known from the prior art and are used in particular to adjust a vehicle seat in the longitudinal direction of the vehicle, ie in the X direction, in order to adapt the seat to the size of the respective seat occupant And / or to move the vehicle seat to, for example, an easy-entry position. Due to manufacturing tolerances, these seat adjusters often require complicated fitting steps and / or are noisy during operation. Contents of the invention [0003] It is therefore the object of the present invention to provide a longitudinal adjuster which does not have the dis...
