摘要:
A vehicle seat includes a seat back frame that has a pair of side frames, and that forms a skeleton member of a seat back, a back board portion that is formed by a resin plate, and that is disposed at a back side of the seat back frame, and a back spring section that is at least partially formed of resin, and that is integral with the back board portion, and that spans between the pair of side frames so as to be directly supported, and that is formed so as to be able to flexurally deform in a load application direction due to load toward a seat back rear side being applied.
摘要:
Two headrest stays-are supported such that, when the tilting amount in the seat front-rear direction of the headrest stays-relative to a seatback frame is within a specified range, the support stiffness of a headrest relative to the seat front-rear direction is reduced in comparison to when the tilt amount is outside the range. The two headrest stays are secured to be swingable in the seat front-rear direction in the headrest.
摘要:
In a seat backboard, a backboard section is formed with a size that enables it to pass through between left and right side frames of a seatback frame. Coupling fixing sections are also provided at the two seat width direction sides of the backboard section, the coupling fixing sections engaging with the front side of the side frames and supported by the side frames. The seat backboard can thereby be attached to the seatback frame from the seat front side, and the degrees of freedom for design can be increased. The seat backboard is also provided with a cover anchor section to which outer periphery anchor portions provided to a seat cover are anchored.
摘要:
A vehicle footrest system allows an occupant seated in a rear seat to brace their feet and that is capable of inhibiting load from concentrating at the heels of an occupant. A footrest system is provided with: a reclining device that rotates an upper end part side of a seatback in the direction of arrow A and holds it at a predetermined angle of rotation; and a slide device that slides a front seat in the direction of arrow B with respect to a vehicle body floor. When an occupant seated in a rear seat uses a footrest portion of the seatback, the reclining device is operated and the upper end part side of the seatback is inclined toward the vehicle front side. Further, the slide device is operated and a slide portion of a seat cushion is moved in a vehicle front-rear direction along a rail portion.
摘要:
Provided is a vehicle seat capable of reliably moving a seat cushion or a seat back to a folded position by remote control without deformation or the like of an armrest. A vehicle seat has a seat cushion, a seat back, and an armrest movable between a use position and a stowed position, in which at least one of the seat cushion and the seat back is movable from a seated position to a folded position, and a remote control restraint element for restraining movement of the movable seat cushion or the movable seat back in the direction of the folded position when the armrest is at the use position is provided.
摘要:
In a vehicle seat including a first seat portion movable between a use position in which the first seat portion is ready for use and a retracted position in which the first seat portion not in use is located, and a second seat portion movable between a use position in which the second seat portion is ready for use and a retracted position in which the second seat portion not in use is located, an actuator mechanism is configured to cause the second seat portion to start moving toward its retracted position at a time when the first seat portion passes a predetermined intermediate position that is on a way from the use position toward the retracted position.
摘要:
In a vehicle rear seat, slits are respectively formed in side wall portions of retainers provided on a vehicle body side and are respectively open at upper end sides of the side wall portions. Hinge pins respectively provided at lower end sides on side portions of a rear seat back are inserted in the corresponding slits to thereby couple the rear seat back to the vehicle body side via the retainers. Furthermore, in the vehicle rear seat, distal end sides of the hinge pins, that is, portions that protrude outward of the rear seat back, are respectively covered with covers attached to the corresponding retainers.
