Problems solved by technology

[0006] On the contrary, if the adjustment gear is connected to the second guide rail by means of a fixed angle welded to the second guide rail or by a support part welded to the second guide rail, the support part is as known, for example, from DE 10 230 514 B4, so that the adjustment The drive unit cannot be easily released from the second guide rail for removal of the longitudinal adjustment unit
This can lead to considerable difficulties when removing a vehicle seat connected to the vehicle floor by such a longitudinal adjustment device from the vehicle

Embodiment Construction

[0050] first, Figure 9 A view of the longitudinal adjustment device 1 is shown, as is conventionally known in the prior art. The longitudinal adjustment device 1 is used for longitudinally displaceable arrangement of a vehicle seat on a vehicle floor, in that a second guide rail 9 to be connected to the vehicle seat is mounted longitudinally displaceably along a longitudinal direction L on a first rail to be connected to the vehicle floor. 4 on a guide rail.

[0051] The longitudinal adjusting device 1 realizes a screw drive by arranging the adjusting drive 2 on the second guide rail 9 and by arranging the screw 6 on the first guide rail 4 via the retaining angles 5A, 5B. The adjusting gear 2 has a spindle nut which engages the external thread of the spindle 6 via an internal thread extending in the longitudinal direction L and is rotatable in order to be able to adjust the second guide rail 9 relative to the first guide rail 4 such that Said spindle nut rolls on the spindl...

Abstract

The invention relates to a longitudinal adjustment device (1) for a dismountable screw device, comprising a bracket (5A), which holds rotation of a spindle (6) with respect to torque load on the spindle during operation of the device. Another bracket (5B) does not hold rotation of the spindle with respect to torque load on the spindle during operation of the device. The brackets are releasably arranged at respective ends (61, 60) of the spindle. A hole is formed at a fixing element (54B) of the latter bracket. The spindle is fixed at the former bracket as an additive material is introduced into the hole. The additive material consists of microencapsulated adhesive. An INDEPENDENT CLAIM is also included for a method for disassembling a longitudinal adjustment device.

Description

technical field [0001] The invention relates to a longitudinal adjustment device for a vehicle seat and a method for dismantling the longitudinal adjustment device. Background technique [0002] Such a longitudinal adjustment device for a vehicle seat has: a first guide rail; a second guide rail mounted displaceably in the longitudinal direction on the first guide rail; A screw rod extending longitudinally that is openly arranged on the first guide rail and an adjusting transmission device arranged on the second guide rail. The adjusting gear comprises a screw nut rotatably engaged with a screw, which can be in rotational motion for adjusting the second guide rail relative to the first guide rail and thus rolls on the screw so that the second The guide rail moves longitudinally relative to the first guide rail. [0003] By means of such a longitudinal adjustment device, the vehicle seat can be adjusted in the vehicle in its longitudinal direction. For this purpose, the sp...
