Patent number: 8596721Abstract: 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.Type: GrantFiled: February 17, 2011Date of Patent: December 3, 2013Assignee: Tachi-S Co., Ltd.Inventor: Hitoshi Ozawa

Patent number: 7984950Abstract: 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.Type: GrantFiled: March 31, 2006Date of Patent: July 26, 2011Assignee: TS Tech Co., Ltd.Inventors: Masayuki Hoshi, Shinji Sugiyama, Masami Yoshida

Patent number: 7963605Abstract: A vehicle seat having a lift structure for adjusting the position of the seat employs a load transfer link (9) to transfer the loads applied to the seat from a lift link (3) and an upper support (2) to a pivot bracket (7), which is typically coupled to the floor of the vehicle. The load transfer link is coupled to the pivot bracket on one end and to the lift link on the opposite end, in order to transfer the load. The lift structure permits movement of a restraint seatbelt with the height adjustment of the vehicle seat, thus reducing the potential for discomfort of the occupant.Type: GrantFiled: July 31, 2006Date of Patent: June 21, 2011Inventors: Ganesh T. Ramaseshadri, William S. Brewer

Patent number: 7959229Abstract: A seat may be obtained with good operability of plural operating members for operating plural adjustable units. A vehicle seat is provided with: a seat lifter, provided to a seat body for sitting on and adjustable by operation force transmitted from a first operating system; a reclining mechanism, provided to the seat body and adjustable by operation force transmitted from a second operating system; and an operation force imparting unit that is provided at a position where it is able to be operated by a seat occupant at a predetermined position on the seat body. The operation force imparting unit is able to independently take up a first state in which a lifter knob is operated and the seat lifter adjusted, and a second state in which the reclining lever is operated and the reclining mechanism adjusted.Type: GrantFiled: January 25, 2007Date of Patent: June 14, 2011Assignee: Toyota Jidosha Kabushiki KaishaInventors: Takahiro Ishijima, Katsuya Ueda

Patent number: 7954897Abstract: In a vehicular seat 10 according to this invention, since a back shell 32 covers a back frame 31, as in the case where the shape of a seat back is formed of the urethane pad, the shape of the seat back is not easily changed. Thus, the passenger can be surely held. Further, since the back shell 32 is displaceably supported for the back frame 31, the back shell 32 is displaced according to the figure or posture of the passenger. This permits the passenger to sit with good riding comfort.Type: GrantFiled: January 18, 2006Date of Patent: June 7, 2011Assignee: NHK Spring Co., LtdInventors: Hideaki Kidokoro, Toshihiko Yamaguchi, Mutsumi Tabata

Patent number: 7934773Abstract: The present document describes an actuated chair for inducing motion with respect to the ground as a function of motion signals synchronized with a video output of a feature length movie. The chair comprises a seat base, and an actuating base for receiving the motion signals. The actuating base comprises three link members, namely a first link member, a second link member and a third link member. Each link member has one translational degree of freedom and two rotational degrees of freedom. The first link member and the second link member are attached to the seat base closer to the rear edge than the third link member. The actuating base further comprises three linear actuators for inducing motion to the seat base. The actuators are fixed to the frame and each actuator is respectively connected to the seat base using a respective one of the three link members.Type: GrantFiled: October 11, 2008Date of Patent: May 3, 2011Assignee: D-Box Technologies inc.Inventors: Steve Boulais, Jean Martin Lizotte, Sylvain Trottier, Stéphane Gagnon

Patent number: 7926769Abstract: 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.Type: GrantFiled: January 24, 2006Date of Patent: April 19, 2011Inventor: John Stenard

Patent number: 7926876Abstract: A chair lift includes a jack movable between lowered and raised configurations and a motor in communication with the jack for moving the jack between the lowered and raised configurations. A switch is in communication with the motor to selectively actuate the motor. A mounting bracket is coupled to the jack to move vertically as the jack moves between the lowered and raised configurations, the mounting bracket having opposed first and second ends. First and second clamping mechanisms are configured for attachment to respective chair legs, the first and second clamping mechanisms being below the mounting bracket. A first flexible connecting link extends between and coupled to the mounting bracket first end and the first clamping mechanism. A second flexible connecting link extends between and coupled to the mounting bracket second end and the second clamping mechanism.Type: GrantFiled: December 30, 2008Date of Patent: April 19, 2011Inventors: Robert F. Zadai, Larry R. Elliott
