Rail of a longitudinal guide with a bearing block of a longitudinal guide and a pivotal flap
View Patent ↗The rail of a longitudinal guide of a longitudinal adjustment device of a motor vehicle seat includes one rail profile, at least one bearing block including a bearing hole, a bearing shaft extending through the bearing hole and a flap, which is pivotal about the bearing shaft. The bearing block is made from the material of the rail profile by cutting out a border of the bearing block and by bending the thus obtained blank for the bearing block about a bending line.
1. A rail of a longitudinal guide of a longitudinal adjustment device of a motor vehicle seat, comprising a rail profile, at least one bearing block-comprising a bearing hole, a bearing shaft extending through said bearing hole and a flap, which is pivotal about said bearing shaft, wherein said bearing block is made from the material of the rail profile by cutting out a border of said bearing block and by bending a blank for said bearing block about a bending line.
2. The rail as set forth in claim 1 , wherein the bearing hole extends through the bending line into an undisturbed region of the rail profile.
3. The rail as set forth in claim 2 , wherein a portion of the bearing hole located in the undisturbed region of the rail profile is larger than a portion located in the bearing block.
4. The rail as set forth in claim 1 , wherein the rail profile is made from a flat material.
5. The rail as set forth in claim 1 , wherein the material of the rail profile has a tensile strength higher than about 600 N/mm 2 .
6. The rail as set forth in claim 1 , wherein the bearing shaft has a diameter of less than about 2.5 mm.
7. The rail as set forth in claim 1 , wherein the bearing shaft has spring properties.
8. The rail as set forth in claim 1 , further comprising two bearing blocks located opposite to each other and having parallel bending lines.
9. The rail as set forth in claim 1 , wherein the cutout is substantially in the shape of a H.
10. The rail as set forth in claim 1 , wherein the bearing shaft extends outwardly away from said bearing block past the bearing hole.
11. The rail as set forth in claim 1 , wherein the rail profile has a receiving bore for an extension of the bearing shaft.
12. The rail as set forth in claim 1 , wherein a distance between the bearing shaft and an outer surface of the rail profile is smaller than a diameter of the bearing shaft.
13. The rail as set forth in claim 1 , wherein the material of the rail profile has a tensile strength higher than about 750 N/mm 2 .
14. The rail as set forth in claim 1 , wherein the material of the rail profile has a tensile strength higher than about 900 N/mm 2 .
15. The rail as set forth in claim 1 , wherein the bearing shaft has a diameter of less than about 2 mm.
