    Abstract: A seat cushion is arranged on a riser. A strut is coupled, at lower end, to the rear end of the riser, and is provided at the back of the seat cushion. The seatback is secured to the strut, and is isolated from the seat cushion. The seatback and the seat cushion can therefore move, independent of each other. The seatback or the seat cushion, or both are lifted or lowered by a lifting/lowering means. Thus, the seatback and the seat cushion are lifted or lowered relative to each other. The lower half of the seatback, which supports the hips and lower ribs in the main, is made narrow than the upper half that supports the shoulder blades in the main. The seat cushion has, in the middle part of the rear end, a U-notch which loosely holds the narrow lower half.

The chair includes: a seat on which a user is seated; a back support configured to support a back portion of the user seated on the seat; and a tilting section interposed between the back support and the seat to couple the seat to the back support. When the user applies a load to bend the back support backward, the tilting section moves the seat upward in proportion to the load applied by the user, and when the load applied to the back support by the user is removed, the tilting section moves the seat downward in proportion to the removed load. As a result, a more comfortable seating feeling may be provided to the user seated on the seat of the chair. In addition, the tilting may be limited as needed by the user. Thus, the chair may further improve the user's convenience.

  • Publication number: 20140070586
    Abstract: A conveyance seat includes: a seat base; a support portion which supports the occupant from the back side; a flip-up mechanism which flips up the seat base; a biasing member which biases the support portion forward; an engagement portion which is engaged with the support portion to hold the support portion in a upright state against the biasing force; a cancel mechanism which cancels the engagement between the engagement portion and the support portion; and a return mechanism which returns the support portion from a state where the engagement with the engagement portion is canceled by the cancel mechanism to a state where the support portion is engageable with the engagement portion. The return mechanism performs the return operation in accordance with the inclination angle of the support portion inclined forward by the biasing member after the engagement between the engagement portion and the support portion is canceled.

  • Patent number: 8662587
    Abstract: A seat assembly for an automotive vehicle is provided with a seat cushion and a seat back pivotally connected to the seat cushion for pivotal movement between an upright seating position and a forwardly folded dump position. A seat track assembly is fixedly secured to the seat cushion for providing a selective fore and aft sliding adjustment of the seat assembly along a first linear path between a full forward position and a full rearward position. A tip slide mechanism is operatively coupled to the seat track assembly and adapted for mounting the seat assembly to a vehicle floor. The tip slide mechanism provides fore and aft movement of the seat assembly along a second curved path transverse to the first linear path between a seating position and an easy entry position to provide access behind the seat assembly.

  • Publication number: 20140049084
    Abstract: A seating unit that includes a linkage mechanism adapted to adjust between closed, extended, and reclined positions is provided. The linkage mechanism includes a seat-mounting plate mounted to a footrest assembly, a back-mounting link and a rear bellcrank both rotatably coupled to the seat-mounting plate, an activator bar that controls a footrest drive link, and a linear actuator for carrying out automated adjustment of the linkage assembly. In operation, a stroke in a first phase of the linear actuator generates a torque on the activator bar. The footrest drive link converts the torque into a laterally-directed force that pushes the footrest assembly into the extended position. A stroke in the second phase acts to push the activator bar forward and translate the seat-mounting plate forward at a consistent inclination angle. The forward translation causes the rear bellcrank to rotate, thereby biasing the back-mounting link rearward into the reclined position.

  • Patent number: 8651576
    Abstract: A multi-position seat for a kayak or other watercraft includes a seat frame and a pivotally connected back support. A pair of side elevation adjusters engages the seat frame on its lateral sides. Each adjuster includes a thumbwheel adjuster within an elevator traveler within a side frame, the traveler engaging a threaded shaft that is held in a fixed rotational position. The frame includes a tunnel structure associated with a front cross member. A strap passes through the tunnel, exits at lateral sides of the front cross member, and connects to lateral sides of the pivotally connected back support. The strap is user-adjustable in length so that the angle of the back to the seat is adjustable. The seat is thereby adjustable in angle front-to-back, can be canted left-to-right, changed in elevation, and the back support can be adjusted in angle and elevation.

  • Publication number: 20130320732
    Abstract: An office chair has a base support, a seat support and a backrest support. A synchronizing mechanism for a correlated seat/backrest movement has the seat support articulated directly on a first pivot bearing of the base support, the backrest support articulated directly on a second pivot bearing of the base support, and the backrest support connected to the seat support via an articulation. The articulation axis of the articulation, as seen in the longitudinal direction of the seat, is in front of the pivot axis of the second pivot bearing, such that a pivoting movement of the backrest to the rear about the pivot axis of the second pivot bearing induces a rotation of the seat support about the pivot axis of the first pivot bearing and thus a lifting movement of just the front region of the seat support.
