Abstract: A seat track assembly comprises a lower track assembly having a lower track and an upper track assembly slidable over the lower track assembly and having an upper track. An elongate upper bracket and an elongate lower bracket enhance resistance to vertical dislocation. The upper bracket is attached to the upper track and has first and second projections which are positioned on opposite sides of the upper track. The lower bracket is attached to the lower track. The upper bracket can slide free of the lower bracket in a normal operating condition, and the first and second projections of the upper bracket are received by the lower bracket to resist vertical dislocation of the upper track when the upper track assembly is subjected to a vertical dislocation force. The first and second projections are preferably unitary extensions of the upper bracket, and are connected to each other by a connecting segment attached to the upper track.

Abstract: A seat track assembly comprises a lower track assembly comprising first and second lower tracks laterally spaced from and aligned generally parallel with one another. Each lower track has a bottom wall and left and right side walls which cooperate with the bottom wall to define a central channel running the length of the lower track. The left and right side walls each have flanges bent over and away from the central channel. An upper track assembly operatively engages the lower track assembly. The upper track assembly comprises first and second upper tracks carried by corresponding first and second lower tracks, allowing the upper track assembly to slide in forward and rearward directions. An elongate upper J-hook is rigidly attached to each upper track, preferably at a top wall of each upper track. An elongate lower J-hook is rigidly attached to each lower track, preferably at a bottom wall of each track.

Abstract: A seat track assembly for a motor vehicle is disclosed, comprising: an upper track sub-assembly having an upper track; a lower track sub-assembly having a lower track and a stop, with the upper track being slidable over the lower track; and a positive engagement inertia latch for resisting axial sliding motion of the upper track sub-assembly relative the lower track sub-assembly in response to acceleration of the gear relative the lower track sub-assembly. The inertia latch preferably comprises a gear being movable between a non-latching position wherein the gear is rotatable in response to axial sliding of the upper track sub-assembly and a latching position wherein in response to a sudden change in velocity the gear engages the stop, locking the upper track sub-assembly with the lower track sub-assembly. The gear can be mounted on an axle. A base is affixed to the lower seat track sub-assembly, having a contoured surface which receives the axle.

Abstract: The legs of the landing gear of a semi-trailer may be automatically extended and retracted by a pneumatically operated actuator adapted to be connected to the crankshaft of the landing gear and adapted to rotate the cross-shaft of the landing gear selectively in either direction at a high or low speed. The crankshaft is rotated by gears and ratchets which are driven by pawls adapted to be reciprocated by an air-actuated cylinder and adapted to be alternately positioned in active and inactive positions. The flow of pressurized air to the cylinder is controlled by a cycle valve and an on-off valve, the latter being capable of turning off the actuator automatically when the legs are fully retracted.

Abstract: A cap for accommodating an overflow of brake fluid from a master cylinder reservoir and for venting the reservoir to atmosphere. The cap is formed from two cup-shaped members adapted to be telescoped together with a snap fit and adapted, when telescoped together, to define an overflow chamber and to define a labyrinth-like passage for venting the chamber to atmosphere.
