  • Patent number: 8596721
    Abstract: In a vehicle seat, two front and two rear links are pivotally connected between a seat cushion frame and a floor of vehicle. Each of the two front links has an arcuate gear region meshed with a corresponding pinion provided to the seat cushion at a point backwardly of that arcuate gear region. Two connecting links are pivotally connected between the respective two front and rear links, such that forward pivot points respective of the two connecting links in the respective two front links are always maintained forwardly of the respective pinions, irrespective of vertical rotation of the two front links. In the case of rear-end collision, such link arrangement allows an excessive backward and downward load to be transmitted through the two connecting links and front links to the two lateral sides of seat cushion frame and dispersed therein, thereby absorbing a corresponding excessive impact.

  • Patent number: 8016258
    Abstract: A seat support assembly includes a base, a plurality of arms each mounted at a first end to the base for movement with respect to the base, and mounted to a seat at a second end opposite the first end for movement with respect to the seat. A torsion spring has a first end defining a length, a second end defining a length, and a coil defining an axis. A first bearing surface abuts the first end of the torsion spring at a first abutment point to define a first moment arm distance. A second bearing surface abuts the second end of the torsion spring at a second abutment point to define a second moment arm distance. An adjustment mechanism simultaneously causes relative movement between the torsion spring and the bearing surfaces to simultaneously change the first moment arm distance and the second moment arm distance.

  • Patent number: 7984950
    Abstract: An automobile seat height adjuster includes a linkage base frame between the seat's side frames and seat brackets so as to be vertically swingable. The base frame has two pairs of linkage members interconnected by respective shafts. Each of the linkage members extends between one of the side frames and one of the brackets so as to be collapsable. A power transmission mechanism transmits to the linkage base frame power generated by operation of an operating knob and causes the linkage base frame to swing vertically, thereby causing the seat to move vertically. Stops on the linkage base frame abut the installation surfaces, limiting downward movement of the seat and keeping the seat in a lowermost position at which side frames of the seat are spaced from the installation surfaces.

  • Patent number: 7926769
    Abstract: A passive/reactive device protests a Payload from injury or damage due to the shock caused by impact or explosion. When the vehicle or structure mounting the Payload receives a shock pulse, the invention limits the acceleration transmitted from the vehicle or structure to the Payload to an acceptably low, user-adjustable level which is substantially constant or is some other user-adjustable force-displacement function. The invention is capable of doing so even when the peak magnitude of the imposed shock is on the order of thousands of G's, with a rise time to peak on the order of microseconds. The invention can be embodied to operate passively, without any external source of power, sensor system, or CPU, although they can be added to improve certain usability features. The invention also absorbs or dissipates the shock energy in substantially the minimum distance possible without exceeding the user-defined acceleration limit on the Payload.
