A headrest support structure has an upper panel, a collar and a sleeve. The upper panel extends in a width direction of a seatback frame at the upper part. The upper panel has a sleeve support part including upper and lower wall parts facing in a direction perpendicular to the width direction. The sleeve support part is in a U-shape open to a side opposite to a seating side in a longitudinal sectional shape. The upper and lower wall parts have upper and lower holes. The collar is in a tubular shape with a through hole. The collar is arranged between the upper wall part and the lower wall part to have the through hole communicate with the upper and lower holes. The sleeve is inserted through the upper hole, the through hole, and the lower hole. A rod-like leg portion of a headrest is insertable in the sleeve.

Headrest support structure and vehicle seat

A vehicle seat slide structure has a movable rail, a fixed rail supporting the movable rail, a slider interposed between the rails, a reinforcing plate fixed to the fixed rail and having a threaded hole having a female thread part, and a pin having a shaft portion, a neck portion, and a head portion. The fixed rail has a first through hole concentric with the threaded hole and having an inner diameter larger than a root diameter of the female thread part. The slider has a second through hole concentric with the first through hole and having an inner diameter larger than that of the first through hole. The shaft portion is inserted through the first through hole and has the male thread part screwed in the female thread part. The head portion supports a periphery part of the second through hole between the head portion and the fixed rail.

Vehicle seat slide structure

A seat lifter structure which can maintain the engagement of the gear of the sector and the pinion of the brake unit and prevent a fall down of the seat back to a front side, even when a large force to a front side is exerted with respect to the seat back is provided. It raises or lowers a cushion seat (ST) by raising or lowering a side frame () built into the cushion seat (ST) with respect to a fixing member (). It is equipped with a brake unit () having a pinion () and attached to the side frame (); a sector () supported to be rotatable with respect to the fixing member () by a first support portion (), supported to be rotatable with respect to the side frame () via a second support portion (), having a gear portion () to be engaged with the pinion () and provided in parallel and facing with respect to the side frame (); and a spacer () having a first surface () facing with the side frame () and a second surface () facing with the sector (), which is installed between the side frame () and the sector ().

Seat lifter structure and vehicle seat equipped with the same

A seat lifter structure which can obtain a rotation of a sector with stable torques is provided. It is equipped with a sector () supported to be rotatable by a support member (), arranged to be facing with a side frame () by being pinched and fixed by a pair of expanded portions () of a tubular shaft member () that is supported to be rotatable by the side frame (), and rotating along the side frame () at a time of raising or lowering the side frame (); a ring shaped spacer () having a first ring shaped abutting surface () facing with the sector () and having a first outer diameter (&#x3d5;), and a second ring shaped abutting surface () facing with the side frame () and having a second outer diameter (&#x3d5;) different from the first outer diameter (&#x3d5;), which is installed between the sector () and the side frame () with an axial line (CL) as a center; and a biasing member () that biases and abuts the sector () to the first abutting surface () and biases and abuts the side frame () to the second abutting surface () by biasing the sector () and the side frame () to approach.

A vehicle seat support frame includes inboard and outboard support assemblies each having a longitudinal base member providing an upstanding strut supporting an elevated front pivot pin. The base member aft end is formed with a downwardly and rearwardly angled brace having a foot pivotally connected to the lower end of a rear link. The link upper end is pivoted to an aft end of a longitudinal carriage having an elongated side slot receiving the elevated front pivot pin, wherein with the link inclined rearwardly the elevated pin is positioned at a front slot limit. A lower rail, fixed on the carriage, slidably supports an upper track member fixed to a seat cushion frame, for seat assembly adjustment. An easy entry dump arrangement allows a seat back to be pivoted from a normal use position to a forward dump position rotating a track cam plate, thereby unlatching the track members for travel to their full forward position, wherein a cam plate finger contacts a latch am forward end follower to pivot the arm out of latched retention of the rear links. The released links are free to rotate forwardly and slide the carriages on their elevated pins to their rear slot limit positions, whereby the seat cushion travels forwardly along a circular arc, about the link lower pivots, inclining the seat cushion forwardly and downwardly to pass under the instrument panel to its easy entry dump position.
