Problems solved by technology

The frame itself is more complicated as it encloses the nuts in a box made of sheet metal and ensures movement of the nuts while compensating for play
Such manufacturing costs are therefore more expensive than using separate nuts

Embodiment Construction

[0023] image 3 A top view of a portion of a guide rail 50 fixed to a vehicle according to an embodiment of the present invention is shown. A fastening hole 55 is provided in the fastening area 60 at each end of the guide rail 50 . The fastening area 60 is arranged on the outside of the profiled part 65 of the guide rail 50 .

[0024] image 3 Section 4-4 of Fig. 4 shows the part of the guide rail 50 fixed on the vehicle from the front view direction. A fastening screw 30 is shown, which may have a bearing washer 35 . The head of screw 30 is not restricted by the profiled part of guide rail 50 when passing, because the hole 55 for screw 30 to pass is arranged on the outside of profiled part (see Figure 5 ). In this way, the diameter of the hole 55 for the passage of the fixing screw 30 can be increased in order to be able to compensate for manufacturing dimensional tolerances in the transverse direction with respect to the translation axis of the guide rail. Furthermore...

Abstract

The invention relates to a vehicle seat runner defining a translation axis. Said vehicle seat runner is attached onto a vehicle floor using an attachment means and comprises attachment areas that engage with said attachment means. Said vehicle seat runner is characterized in that the attachment areas are sized and arranged so as to compensate, transversely to the translation axis of the runner, the manufacturing tolerances of the seat and said attachment means and so as to enable said attachment means to engage with the runner, transversely to the translation axis of the runner.

Description

technical field [0001] The present invention relates generally to rails for vehicle seats adapted for mounting on a motor vehicle. Background technique [0002] In the prior art, guide rails for vehicle seats are known which allow the longitudinal position of the seat in the vehicle to be adjusted by translating the seat in the guide rail. These rails are usually assembled in two on the seat, and the "seat-rail" part is then sent to the factory where the motor vehicle is manufactured, where the "seat-rail" part will be mounted and secured to the vehicle. The assembly is usually screwed by means of screws through fastening holes provided for this purpose on the guide rail. Corresponding fastening nuts are accommodated in the vehicle body. Manufacturing methods for the seats, rails, and body of a vehicle are known to induce variations in manufacturing dimensions, which means designing methods that compensate for the inherent dimensional tolerances of manufacturing. The hole...
