Longitudinal adjuster for a seat and seat

A longitudinal adjuster for a vehicle seat, comprising:

• a first fixed lower track and
• a first upper track slidable coupled to the first lower track,
• wherein the first upper track and first lower track coupled together form a first pair of rails,
• a second pair of rails comprising a second fixed lower track and a second upper track slidable coupled to the second lower track,
• an adjustment device coupled to the first pair of rails for longitudinally adjusting the upper tracks of the first pair of rails and second pair of rails relative to the lower tracks of the first pair of rails and second pair of rails, respectively,
• wherein the adjustment device comprises a rack and pinion drive that is located laterally between the first pair of rails and second pair of rails,
• wherein the rack and pinion drive comprises a pinion that is coupled to the first upper track,
• wherein the adjustment device is arranged at least partially above the first pair of rails and extends at least partially along the length of the tracks,
• a latch mechanism coupled to the first pair of rails to latch the first upper track relative to the first lower track,
• wherein the latch mechanism has a pin and a latch plate,
• wherein the latch plate extends across the entirety of the first upper track and at least partially across the first lower track,
• wherein the latch plate is adapted to selectively engage with recesses in the first lower track,
• wherein the adjustment device further comprises a driving unit to power the rack and pinion drive upon release of the latch mechanism,
• wherein the adjustment device further comprises a clutch unit to connect or disconnect the driving unit and the rack and pinion drive upon release or latching of the latch mechanism,
• wherein the driving unit is located above and laterally centered on the first pair of rails and is attached to the clutch unit,
• wherein the clutch unit is attached to the driving unit and pinion and is located above the first pair of rails, and
• an electromechanical device coupled to the latch mechanism,
• wherein the electromechanical device is configured to bias the latch mechanism between a release position and a latch position, and upon release of the latch mechanism the adjustment device is actuated to drive the first upper track relative to the first lower track.

A longitudinal adjuster for a vehicle seat comprising:

• a fixed lower track and
• an upper track slidable coupled to the lower track,
• wherein the upper track and lower track coupled together form a pair of rails,
• an adjustment device coupled to the pair of rails for longitudinally adjusting the upper track relative to the lower track,
• wherein the adjustment device comprises a rack and pinion drive,
• wherein the rack and pinion drive comprises a toothed rack and a pinion,
• wherein the adjustment device further comprises a driving unit that is coupled to the pinion via a clutch unit,
• wherein the adjustment device is arranged laterally distant from the pair of rails, and
• a mounting bracket that couples the driving unit, and thus the adjustment device, to the upper track,
• wherein the mounting bracket runs perpendicular to a vertical axis of the pair of rails,
• wherein the mounting bracket covers at least part of the upper track, the pinion, the driving unit, and the clutch unit.
