  • Patent number: 9771009
    Abstract: A vehicle seat that can reduce manufacturing costs while increasing assembling rigidity of an elastic spring for supporting an occupant is described. A vehicle seat includes an elastic spring bridged between a front frame and a rear frame to support an occupant. A hook member is attached to a rear end portion of the elastic spring to be hooked to the rear frame. The hook member includes a hook body extending along an outer periphery of the rear frame and a projection projecting from a front edge of the hook body toward the rear frame and formed to have a width smaller than a width of the hook body. A through-hole is formed in a portion of the hook body, which is opposed to the projection. The through-hole has a width larger than a width of the projection and a length larger than a projecting length of the projection.

  • Patent number: 6260223
    Abstract: Spring sets each include a pair of coil springs joined together by a connecting wire and are encased in individual fabric pockets such that the connecting wire joining the coil springs spans an otherwise empty fabric pocket. A spring unit, mattress or the like includes a number of such pocketed spring sets with the connecting wire being alternately positioned near a top face or a bottom face of the spring unit. The pocketed coil spring unit can be used to form a mattress or other spring assembly of pocketed coil springs wherein every third pocket is left empty. The connecting wire spreads the load across the empty pocket and distributes the load to the adjacent springs. The absence of one-third of the springs that are normally in a mattress drastically reduces material costs without diminishing performance.

  • Patent number: 6170143
    Abstract: A handle for a mattress border is anchored with spaced grommets in the border against which anchors on the handle ends may bear. The anchors are designed to allow a leading end of the handle to be drawn through grommet opening. A back strap between the grommet openings is shaped to allow clamping to move the grommet opening to aligned position. To allow the drawing of the anchors through the grommet opening, at least one of the anchors is provided with first couplings. A puller rod is designed to be inserted through at least one of the grommet openings. The puller rod is provided with second couplings, designed to cooperate with the first couplings to achieve the pulling function.

  • Patent number: 5373793
    Abstract: An adaptor housing assembly for mounting an adjustable height work surface to a wall panel of an open office furniture system. The wall panel has a pair of vertical slotted standards which are adapted to receive the hooks of a mounting bracket. The adaptor housing assembly mounts a height adjustable work surface to the vertical slotted standards of the wall panel by clamping a mounting bracket to an adaptor housing in which is mounted a height adjustment mechanism having a frame which is connected to the work surface. The adaptor housing is fixed with respect to the wall panel and the frame of the height adjustment mechanism moves vertically with respect to the wall panel to raise and lower the work surface. The channel guides the moving members of the mechanism to which the work surface is mounted. The adaptor housing has a pair of elongated flanges extending outwardly from one end of the adaptor housing to form a slot which receives an elongated plate having tapped holes.

  • Patent number: 5369822
    Abstract: A bent wire spring unit having a spaced pair of foot portions and a spring member extending upwardly from each foot portion. Each spring member is formed of a series of torsion bars and connector bars interconnected by bends in the spring wire. The spring members are connected at their upper ends by a locking member or portion having first and second pairs of bends in the spring wire and two locking bars extending from the second pair of bends. The locking bars are linear segments of wire angled downwardly such that they converge into a connecting bend. The locking bars and the connecting bend lie in a single plane and the distal ends of the locking bars and the connecting bend extend significantly below an uppermost torsion member of each spring member. A spring assembly is disclosed which includes the bent wire spring unit attached to a wire grid at its upper end and a base frame at its lower end.

  • Patent number: 5197354
    Abstract: An intermittent drive mechanism is provided for intermittently driving an output shaft with an input shaft that has an axis that intersects the axis of the output shaft at an angle. A driving element on the input shaft couples with a driven element on the output shaft through pairs of corresponding accelerating and decelerating pin and slot combinations which engage each other intermittently at the surface of an imaginary sphere which is centered at the intersection point of the shafts. Embodiments are provided both with and without intermittent driving gears on the elements to maintain the output shaft rotation at constant maximum velocity through a predetermined arc. The slots are curved, preferably in circular arcs, so as to optimize acceleration and the rate of change of acceleration (jerk), particularly as the output shaft approaches and leaves the point of maximum angular velocity.
