Patent ID: 8376460

Claim:
A seat track assembly comprising: a lower channel ( 1 ) fixed to a floor, said lower channel comprising: a lower surface having a plurality of spaced slots ( 21 ); an upper channel ( 2 ) slidable over said lower channel ( 1 ), fixed to lower structure of a seat, said upper channel ( 2 ) comprising: an upper surface having a plurality of spaced slots ( 31 , 36 ); a latch bracket ( 3 ) fixed to said upper channel ( 2 ); two latch pins ( 4 ) placed between said lower channel ( 1 ) and said upper channel ( 2 ), each of said latch pins comprising: an extrusion ( 45 ) oriented at right angles to a plane containing said upper and lower channels, three pins ( 47 ) for engaging into said slots ( 21 ) of said lower channel ( 1 ), two side tongues ( 46 ) for engaging into said slots ( 31 ) of said upper channel ( 2 ), each tongue being provided with a spring ( 11 ) thereon, a central tongue ( 48 ) for engaging into one of said slots ( 36 ) of said upper channel ( 2 ); a lever( 5 ) adapted to slide parallel to said upper and lower channels and operably connected to said latch bracket ( 3 ) and latch pins ( 4 ), said lever comprising: two extruded surfaces ( 51 ) extending sideways from said lever for pushing a respective said extrusion ( 45 ) of each said latch pin ( 4 ), a lever handle ( 52 ) protruding through said upper channel ( 2 ); said spring ( 11 ) being placed on each of said side tongues ( 46 ) of said latch pin ( 4 ); whereby in a latching position, the said pins ( 47 ) of one of the latch pins ( 4 ) engage into said slots ( 21 ) in the lower channel ( 1 ) to prevent the upper channel ( 2 ) from sliding over said lower channel ( 1 ), thereby disallowing movement of the seat and when the lever handle ( 5 ) is pulled, the extruded surface ( 51 ) of the lever ( 5 ) pushes the extrusion ( 45 ) of the engaged latch pin ( 4 ) upwards against the spring pressure to disengage the pins ( 47 ) from the slots ( 21 ) in the lower channel ( 1 ) and engage the tongues ( 46 , 48 ) with the slots ( 31 , 36 ) to achieve an unlatching position, thereby allowing the upper channel ( 2 ) to slide over the lower channel ( 1 ) to enable movement of the seat.
