A motor vehicle seat fitting (10) includes a first fitting part (11) and a relatively rotatable second fitting part (12), which are connected to each other via a gear unit or can be locked. A third fitting part (74) is mounted on a bearing ring (71) in a pivotal manner about an axis (A) relative to the first fitting part. The bearing ring is fixed to the first fitting part. The third fitting part (74) can be locked with the first fitting part or a component rigidly connected thereto. A pawl (80) is mounted on the third fitting part in a first hinge point (D1). The bearing ring (71) has multiple run-on cams (71a) which interact with multiple elevations (74a) of the third fitting part. A free clearance, in the radial direction between the bearing ring (71) and the third fitting part, is minimized when the pawl (80) is locked.

A vehicle seat including: a framework of a seat back, which includes an outer side frame located on an outer side of a vehicle and an inner side frame located on an inner side of the vehicle; a lower panel bridged between a lower portion of the outer side frame and a lower portion of the inner side frame; and a reinforcing member including: a first part attached to a surface of the outer side frame facing the inner side frame and extending along a longitudinal direction of the outer side frame; and a second part connected to the first part at one end thereof and extending toward the inner side frame, wherein, in a front view, the second part is located lower than an upper end of the lower panel.

A locking device for locking two assemblies of a vehicle seat together comprises a blocking element which has a supporting surface, and a locking element which is movable with respect to the blocking element, said locking element having an end face and facing the supporting surface of the blocking element with the end face in a locked position of the locking device, wherein the locking device is unlockable by moving the locking element. Additionally provided is a surface element which is applied to the blocking element to at least partially cover the supporting surface or to the locking element to at least partially cover the end face.

A seat recliner assembly for a vehicle may include first and second recliner hearts, a hand lever, and a cross member. The first recliner heart may be mounted to a bracket. The second recliner heart may be mounted to another bracket. The hand lever may be mounted to the first recliner heart and may be rotatable relative to the brackets to move the first recliner heart between a locked state and an unlocked state. The cross member may be connected to the first and second recliner hearts and may transmit torque from the hand lever to the second recliner mechanism to move the second recliner heart with the first recliner heart between the locked and unlocked states. The cross member may include an aperture extending through an entire longitudinal length of the cross member.

A hardware system, for a vehicle seat, includes a fitting (10) having a first fitting part (11) and a second fitting part (12), which can be locked to one another and can rotate in relation to one another about an axis (A), a transmission rod (7) and a hand lever (5), the actuation of which rotates the transmission rod (7). The fitting is unlocked via a rotation of the transmission rod against a total characteristic torque (M.sub.overall), produced from a sum of a first characteristic torque (M.sub.35), generated by a spring assembly (35), and a second characteristic torque (M.sub.61), generated by spiral springs (61). A first component (63) is rotationally fixed to the transmission rod and a second component (64) moves relative thereto during unlocking. The spiral springs (61) act between the first component (63) and the second component (64). A vehicle seat is provided having the hardware system.

A detent fitting for a motor vehicle seat includes a first fitting part (11) and a relatively rotatable second fitting part (12) and catches (16) guided by one fitting part between a locked state and an unlocked state to lock the detent fitting upon interacting with a gear ring of another fitting part. A third fitting part (74) is pivotably mounted and is lockable with a detent plate (115) fixed to the first fitting part or with the first fitting part by a pawl (80) which is mounted in a hinge point on the third fitting part. The third fitting part, a locking cam (90) with a hinge point on the third fitting part, a coupling (98) connected to the locking cam with a hinge point and the pawl with a hinge point define a four-link chain. A vehicle seat with at least one such detent fitting is also provided.

A hinge mechanism for a motor vehicle seat allowing angular adjustment of a backrest relative to a seating portion. The hinge mechanism includes first and second hinge plates, a control member moving locking elements and biased to a locking position by first springs, and a drive shaft biased to a first rest position by second springs. The second springs are housed between the first and second hinge plates and are supported on the first plate.

A vehicle seat includes paired right and left recliners; operating pins respectively inserted through the recliners in an axial direction, and rotated about axes thereof to respectively unlock the recliners; and a rod that integrally connects the operating pins. One operating pin includes an operating shaft portion inserted through, and connected to one recliner, and a connection portion that contacts the rod and is connected to the rod. An insertion depth of the operating shaft portion with respect to the one recliner can be changed by moving the operating shaft portion between a first position in which the connection portion contacts the rod to be connectable to the rod, and a second position in which the connection portion is away from the rod in the axial direction. The operating shaft portion is connected to the one recliner so as to operate the one recliner, in the first position.

A vehicle seat reclining device includes a lock mechanism. The lock mechanism includes first and second members, which are rotational relative each other, first pawls, and a cam, which moves the first pawls in the radial direction and unlocks or locks the same. The vehicle seat reclining device includes a memory ring, which integrally rotates with the first member or the second member through engagement, partial engagement, or disengagement from the first pawls, an engaging projection, which is located in an accommodating recess of the second member and protrudes radially inward, and a rotation permitting section located on the outer circumferential surface of the memory ring. When the rotation permitting section allows the engaging projection to move, relative rotation within a predetermined rotation range is permitted between the second member and the memory ring.

The present invention relates to a rod adapter for operating recliner and a seat reclining device comprising the same, where the seat reclining device comprises a fixed frame; a rotating frame rotatably coupled to the fixed frame; a recliner coupled to the fixed frame at one side and to the rotating frame at the other side to adjust rotation angle of the rotating frame; a shaft rod penetrating the fixed frame, the rotating frame and the recliner; a recliner lever provided rotatable around a shaft receiving part disposed coaxially to an end part of the shaft rod; and a rod adapter disposed between the shaft rod and the recliner lever and having a rod inserting recess part where the shaft rod is inserted and a lever shaft part which is inserted into the shaft receiving part of the recliner lever so that it intermediates between rotations of the shaft rod and the recliner lever. Therefore, compatibility between the recliner lever and the shaft rod as components of the seat reclining device can be enhanced.
