Abstract: In a slide structure employing balls comprising an outer element formed by a U-section element 1 provided with flanges 2, the inner element 8 is constituted by a tube which is deformed in such manner as to include two lateral wings 10 each one of which is between two concave grooves for receiving the balls 16. Beyond the portion of the tube deformed in this way, the tube is bent and devoid of flanges so as to enable it to extend through the opening 3 of the U-section element 1 before resuming its initial section. The tube terminates in fixing tabs. Sheared and deformed portions which are evenly spaced apart along a central longitudinally extending boss 18 of the inner element constitute a rack for driving or locking the inner element relative to the outer element.

Abstract: A bracket assembly constructed according to one embodiment includes a pair of identical L-shaped brackets arranged for selectively positioning a seat at three different heights. An alternate embodiment of the bracket assembly includes a pair of tubular brackets which are rectangular in cross section and optionally mountable to a horizontal frame surface with either their long side or their short side against the surface for selectively positioning a seat in a low or a high position.

Abstract: A longitudinally adjustable vehicle seat construction and method of making the same are provided, the seat construction comprising a lower structural seat frame unit, a seat cushion unit supported by the lower seat frame unit, and an upper slide unit carried by the construction for sliding longitudinally on a fixed lower slide unit carried by a vehicle to thereby permit longitudinal adjustment of the seat construction in the vehicle, the upper slide unit comprising a structural part of the lower structural seat frame unit.

Abstract: A two-part seat assembly for a motorcycle like vehicle has an operator's seat that is hingedly mounted to enable adjustment of its angle of inclination, and thereby to enable alteration of the operator's body attitude. Skirt portions are provided on the operator's seat to conceal the mechanism by which adjustment of the seat position is achieved, and to hide the frame parts and the concavity in which the operator's seat resides.

Abstract: An adjustable vehicle seat has an upholstered seat frame and an upholstered back frame. The seat frame is mounted on the vehicle frame independently of the back frame and is adjustable in a heightwise, longitudinally and in an inclined manner with respect to the vehicle frame. The upholstery is displaceable with respect to the seat frame, as well as the back frame.

Abstract: A child stroller has a back and a leg rest pivotally coupled to a seat so that the angles between the seat and leg rest or back can be changed. The seat can be slidably moved relative to the back to provide an adjustable length seating surface. The height of the back and length of the leg rest are both adjustable. The seat, back and leg rest are locked into position after the desired adjustments are made.

Abstract: In an assembly of a seat frame for an automobile seat, slide rails therefor enabling the longitudinal adjustment of the seat position, and a locking device therefor, the slide rails, particularly the upper slide rail, is contained within the seat frame, and the locking device is mounted on the seat frame.

Abstract: A chair apparatus particularly useful by crew members in oceangoing powerboats has a seat assembly attached to a support flange assembly. The support flange is adjustably coupled to an upstanding support member which is fixed to a support surface to allow the seat assembly to be moved vertically along the upstanding support member. The side portions of the seat assembly are adjustable in and out to accommodate the width of a particular occupant. A posterior support extension is hinged to the front portion of the seat assembly to provide increased sitting space when, for example, the boat is not racing. The posterior support extension is rotated downward and out of the way when the boat is racing. A non-rebound impact absorption pad is attached to the interior surfaces of the seat assembly. The pad has a plurality of layers of visco-elastic foam, each layer having a different degree of firmness.

Abstract: An invalid chair has a seat divided into a central saddle portion and a leg supporting portion. The saddle portion is rigidly connected with the backrest having two armrests. The leg supporting portion is hingedly connected at its front end to the base frame of the chair and a linkage is provided, so that when lifting the saddle portion it will leave the leg supporting portion and carry the person sitting on the saddle portion with his hands on the armrests until the legs of the person are substantially straightened out with his feet resting on the floor.

Abstract: Juvenile toy vehicle with a braking arrangement including front and rear axles supporting front and rear wheels, respectively, a pipe frame having the front and rear axles mounted in the front and the rear ends thereof, respectively, a sprocket wheel having a crank shaft provided with a pair of pedals and positioned on the pipe frame, another sprocket wheel rigidly mounted on the rear axle and linked with the crank shaft sprocket wheel by the intermediary of an endless chain, and a steering wheel linked with the front axles to permit change of a running direction of the vehicle.One of the rear wheels is rigidly disposed on the rear axle for integral rotation with the rear axle sprocket wheel, while the other rear wheel is journaled rotatably on the rear axle. The rear axle and the crank shaft are rotatably supported between an opposed pair of complimentary bush halves which are surrounded and held together by a fixture rigidly secured on the pipe frame.

Abstract: An adjustable wooden studio bench has four legs, the upper portions of which are connected by a pair of horizontal top rails provided with vertical openings through which the legs extend. A horizontal footrest rail like the top rails is mounted on the lower portions of the legs. The front legs are connected with the back legs by means of cross bars with vertical openings for the legs. The cross bars may support a tray. Each rail and bar has a vertical slot through each end extending from the opening out through the adjacent end to form a pair of horizontally spaced jaws that are drawn toward each other by a fastener extending through them to clamp the rails and bars to the legs. When the fasteners are loosened, the rails and bars can be moved vertically on the legs. The top rails support a seat that is slidable lengthwise of them.
