Abstract
In a drive (1) for a vehicle seat adjuster (3), having a manually pivotable drive lever (15), which can be deflected out of a neutral position in order, after an element (35) has engaged in a drive wheel (51), to produce a directed rotational movement of an output element (63), at least one sliding element (35) which is moveable in a translatory manner is provided as the element which is to be engaged.
Claims25
A drive for a vehicle seat adjuster, the drive comprising:
- at least one sliding element mounted for moving in a translatory manner into engagement with a drive wheel in response to a drive lever being pivoted, wherein the drive lever is mounted for being manually pivoted relative to the sliding element, and an output element is mounted for rotating in response to the drive lever being pivoted while the sliding element is in engagement with the drive wheel;
- and
- a rotational element that is in contact with the sliding element and is mounted for rotating in response to the drive lever being pivoted.
A drive for a vehicle seat adjuster, the drive comprising:
- at least one sliding element mounted for moving in a translatory manner into engagement with a drive wheel in response to a drive lever being pivoted, wherein the drive lever is mounted for being manually pivoted relative to the sliding element, and an output element is mounted for rotating in response to the drive lever being pivoted while the sliding element is in engagement with the drive wheel;
- a guide for guiding movement of the sliding element in a radial direction, wherein the drive wheel rotates about an axis in response to the drive lever being pivoted while the sliding element is in engagement with the drive wheel, and the radial direction extends outwardly from the axis;
- and
- means for frictionally holding a carrier plate in a fixed position while the sliding element moves in the translatory manner into engagement with the drive wheel, wherein the guide is part of the carrier plate.
1 more element
A drive for a vehicle seat adjuster, the drive comprising:
- at least one sliding element mounted for moving in a translatory manner into engagement with a drive wheel in response to a drive lever being pivoted, wherein the drive lever is mounted for being manually pivoted relative to the sliding element, and an output element is mounted for rotating in response to the drive lever being pivoted while the sliding element is in engagement with the drive wheel;
- and
- control teeth for disengaging the sliding element from the drive wheel while the drive lever is returned from a deflected position to a neutral position.
A drive for a vehicle seat adjuster, the drive comprising:
- at least one sliding element mounted for moving in a translatory manner into engagement with a drive wheel in response to a drive lever being pivoted, wherein the drive lever is mounted for being manually pivoted relative to the sliding element, and an output element is mounted for rotating in response to the drive lever being pivoted while the sliding element is in engagement with the drive wheel;
- and
- an overload safeguard that is between the drive wheel and the output element for separating the drive wheel from the output element in response to a predetermined load being exceeded.
A drive for a vehicle seat adjuster, the drive comprising:
- at least one sliding element mounted for moving in a translatory manner into engagement with a drive wheel in response to a drive lever being pivoted, wherein the drive lever is mounted for being manually pivoted relative to the sliding element, and an output element is mounted for rotating in response to the drive lever being pivoted while the sliding element is in engagement with the drive wheel, and wherein the drive drives a self-locking gear.
A combination, comprising:
- a drive including at least one sliding element mounted for moving in a translatory manner into engagement with a drive wheel in response to a drive lever being pivoted, wherein the drive lever is mounted for being manually pivoted relative to the sliding element, and an output element is mounted for rotating in response to the drive lever being pivoted while the sliding element is in engagement with the drive wheel;
- and
- a vehicle seat, wherein the drive drives a height adjuster of the vehicle seat.
