Disclosed is a low-posture zero-gravity seat frame capable of being adjusted in multiple directions. A first left front connecting rod has a lower end hinged to a left slide rail front bracket and an upper end hinged to one end of a second left front connecting rod, and the other end of the second left front connecting rod is hinged to a front horizontal tube. A second toothed plate driving device is able to adjust the height of a seat framework through the movement of a rear horizontal tube. A seatbelt retractor is disposed below the seat framework. The seat frame can realize zero-gravity adjustment, occupies a small space, and can fulfill low-posture seat arrangement.

The invention relates to a device for adjusting a seat position for a vehicle seat, which comprises at least one support element for a seat part and can be connected to a seat substructure, the device comprising at least one first leg and at least one second leg, the legs being rotatably arrangeable on the seat substructure and the at least one support element, the at least one first leg and the at least one second leg being mechanically coupled by a connecting element, the length of which can be modified, wherein a modification of the length of the connecting element causes a change in an angle of inclination θ of the support element.

A vehicle seat in accordance with the present disclosure includes a seat bottom and a seat back. The seat back is coupled to the seat bottom to move relative to the seat bottom. The seat bottom is coupled to a floor of a vehicle and configured to move relative to the seat back.

A vehicle seat includes: a seat frame that serves as at least a portion of a skeletal structure; a fixed bracket that is fixed on the indoor wall, the fixed bracket including a connection part having a connection surface that is substantially orthogonal to a seat width direction and extending in a substantially vertical direction; a link member in which one end is swingably connected with the connection part and the other end is connected with the seat frame, the link member being swingable in a direction substantially parallel with the seat width direction set as a swinging center axis; and a regulation part which extends from the connection part in a direction substantially parallel with the swinging center axis, the regulation part being configured to regulate, by abutting on the link member in the seat front-and-rear direction, that the link member swings beyond a preset swinging range.

A power seat slide device capable of changing not only to an electric operation but also to an manual operation, and preventing half-lock in spite of a manually operable structure. For front-rear movement, a rack attached to a lower rail and a pinion meshed with the rack are used, and a driving force of a motor is transmitted to the pinion, which enables the use in an electric mode. As no slide screw is used, while the motor is not energized, rotating the pinion causes an output shaft of the motor to rotate, so that manual adjustment becomes possible.

A connecting element (3) for adjusting the height of a vehicle seat (1) includes an angular element (3.1) with a first leg (3.1.1) having a seat part side receiving opening (3.1.5) and an opposite rail side end receiving opening (3.1.4), and a second leg (3.1.2) angled relative to the first leg (3.1.1) and a tooth element (3.2). The seat part receiving opening (3.1.5) is situated in a connection area of the first leg (3.1.1) and of the second leg (3.1.2). The tooth element (3.2) has a first section (3.2.1) configured as a circular arc with toothing (V2) that is connected at an end side to the second leg (3.1.2) and a second section (3.2.2) that is angled from the first section (3.2.1) in the direction of the receiving opening (3.1.5) on the side of the seat part and is connected to the first leg (3.1.1) at the end side.

A locking apparatus of a buckle of a seat belt for vehicles includes a sector gear bracket configured to be integrally coupled to a rear pipe which is coupled to a seat cushion frame, wherein the sector gear bracket has: an arc-shaped locking hole; and a sector gear arranged along the locking hole as an internal gear; a pole bracket located at one side of the sector gear bracket, wherein the pole bracket has a shaft part which is configured to pass through the locking hole and the seat cushion frame and then be integrally coupled to a lower end of the buckle; and a lock gear arranged on the pole bracket as an external gear.

A clutch unit includes an operation lever, an operation bracket, an output shaft member, an input-side clutch, an output-side clutch, and a housing. An input-side outer ring member of the input-side clutch is a member including a bottom part and an outer ring part. A part of the outer ring part is a thick part. The thickness of the thick part in the radial direction is larger than the thickness of a non-thick part in the radial direction.

An automobile seat integrated with height adjustment and angle adjustment comprises a seat body comprising a pedestal skeleton and a backrest skeleton, a height adjustment mechanism comprising a bottom support, a rear connection rod, an upper connection rod and a front connection rod and an angle adjustment mechanism comprising the bottom support, an angle adjustment connection rod, a driving connection rod, a front connection rod and the upper connection rod, the bottom support, the front connection rod and the upper connection rod are common parts of the height adjustment mechanism and the angle adjustment mechanism, the bottom support, the rear connection rod, the upper connection rod and the front connection rod are successively adjacently connected by rotating pairs, and the rear connection rod is connected with a height adjustment driving source which drives the rear connection rod to move when working to realize the height adjustment of the automobile seat.

The present disclosure relates to a seat structure for a vehicle, in which a swivel upper plate module is configured by integrating and modularizing a swivel upper plate part, a swivel reinforcing member part, and set bracket parts, the swivel upper plate module is coupled to a seat cushion frame, and left, right, and rear sides of the swivel upper plate module are positioned inward from left, right, and rear sides of a seat bracket coupled to a seat, such that a design of a lower side of the seat may be slim.
