Abstract
A seat track mechanism for a vehicle seat. The seat track mechanism may include an upper track, a lower track, a lever, and a retainer bracket. The lever may be pivotable between a first position and a second position and may have a latch arm. The retainer bracket may define a slot that may receive the latch arm to hold the lever in the second position.
Claims20
A seat track mechanism comprising:
- a lower track;
- an upper track that is received in the lower track and is slidable with respect to the lower track;
- a lever that is received in the upper track and is pivotable between a first position and a second position, the lever having a latch arm that extends toward the lower track;
- and
- a retainer bracket that is received in the lower track, wherein the retainer bracket defines a slot that receives the latch arm to hold the lever in the second position, wherein the retainer bracket has a first retainer bracket end surface, and a first retainer bracket side wall that extends from a bottom retainer bracket wall that is disposed on a bottom wall of the lower track, the first retainer bracket side wall having a first portion that extends from the bottom retainer bracket wall and a second portion that extends from an end of the first portion such that the second portion is spaced apart from the bottom retainer bracket wall, the second portion having an upper surface, a lower surface disposed opposite the upper surface, and a ramp surface that extends from the lower surface toward the upper surface such that the ramp surface becomes progressively closer to the lower surface un an axial direction that extends away from the first retainer bracket end surface, wherein the ramp surface is configured to guide the latch arm into the slot, wherein the latch arm contacts the second portion and is spaced apart from the first portion when the latch arm is received in the slot.

A seat track mechanism comprising:
- a lower track;
- an upper track that is received in the lower track and is slidable along an axis with respect to the lower track;
- a lever that is pivotally coupled to the upper track and has a latch arm, the lever having a center portion, a first arm and a second arm that are spaced apart from each other and extend from the center portion, a first cross wall that extends from the first arm to the second arm, a second cross wall that extends from the first arm to the second arm, and an actuation feature that is configured to facilitate actuation of the lever, wherein the latch arm extends from the first cross wall and the actuation feature extends from the second cross wall through the upper track;
- a retainer bracket that is received in and fixedly secured to the lower track, wherein the retainer bracket defines a slot;
- and
- a track locking mechanism that has a lock plate that is arranged between the upper track and the lower track, wherein the lock plate is moveable between a locked position in which the lock plate engages the upper track and the lower track to inhibit axial movement of the upper track with respect to the lower track and an unlocked position in which the lock plate is disengaged from the lower track to permit axial movement of the upper track with respect to the lower track, wherein the lever is configured to engage the lock plate to actuate the lock plate from the locked position to the unlocked position and the latch arm holds the lock plate in the unlocked position.
