Abstract

A restoration and energy absorption mechanism for a seat backrest, said mechanism comprising a seat base arm plate (100) and an angle adjuster lower connecting plate (300). The seat backrest is mounted on the angle adjuster lower connecting plate by means of an angle adjuster (400). The angle of inclination of the seat backrest can be adjusted by means of the angle adjuster. A first position (310) of the angle adjuster lower connecting plate is hinged to a first position (110) of the seat base arm plate by means of a pin shaft. A second position (320) of the angle adjuster lower connecting plate is provided with a waist-like hole (340). An energy-absorbing fastening element (620) passes through a first position of the waist-like hole and through a locking piece (500) and is locked at the second position (120) of the seat base arm plate. The locking piece can perform destructive unlocking by relying on an instantaneous external force, thereby releasing the position-limiting state between the backrest and a cushion, such that the seat can be restored during collision, and energy absorption is carried out by means of material extrusion deformation during the restoration process. The described restoration and energy absorption mechanism has a simple structure and low costs and is capable of ensuring the static strength of the backrest. The present invention further comprises an automobile seat provided with a restoration and energy absorption mechanism.

Abstract

An air outlet device (AV). A toggle button (40) is configured to deflect around a first direction to drive front-row blades (201) to rotate so as to adjust one airflow direction in the horizontal direction and the vertical direction, and to deflect around a second direction perpendicular to the first direction to drive rear-row blades (301). When the toggle button (40) deflects between a first position and a second position around the second direction, the rear-row blades (301) are driven to rotate so as to adjust the other airflow direction in the horizontal direction and the vertical direction. When the toggle button (40) deflects from the second position to a third position around the second direction, the rear-row blades (301) are driven to rotate so as to limit air flow from passing through.

Abstract

A thermoplastic fiber mesh structure and an automotive interior trim part. According to the thermoplastic fiber mesh structure (2a, 2b, 2c, 2d), a support structure is formed by means of fiber filaments (21a, 21h, 21i, 21j, 21k, 21l, 21m, 21n, 21q) molten and bonded together by themselves, and the fiber filaments are made of a thermoplastic elastomer material. The automotive interior trim part comprises the thermoplastic fiber mesh structure, and face covers and/or fabrics (1a, 1b, 1c, 1d) tightened onto the thermoplastic fiber mesh structure. According to the thermoplastic fiber mesh structure, the thermoplastic elastomer material is molten and extruded to form a three-dimensional mesh structure, the support structure is formed, and the thermoplastic fiber mesh structure has the characteristics of high resilience and recyclability, such that the automotive interior trim part gives consideration to environmental protection, air permeability and light weight while ensuring the support performance and the comfort. The thermoplastic material is subjected to a physical reaction, instead of a chemical reaction, in the melting and extrusion process, such that the stability is better in the preparation process, and the product is more uniform and controllable. Considering that a conventional face cover foaming and tightening form cannot be suitable for the thermoplastic fiber mesh structure, the automotive interior trim part provides a brand-new tightening form to match the coating of the thermoplastic fiber mesh structure.

Abstract

The present invention relates to an air outlet device. When rotating forwards in a first angle range, an electric motor drives a horizontal air guide member to move from a first position to a second position, and when rotating backwards in the first angle range, the electric motor drives the horizontal air guide member to return from the second position to the first position, so as to facilitate the adjustment of a horizontal air blowing direction. When rotating backwards in a second angle range, the electric motor drives a vertical air guide member to move from a third position to a fourth position, and when rotating forwards in the second angle range, the electric motor drives the vertical air guide member to return from the fourth position to the third position; and in the process, the horizontal air guide member remains stationary, so as to facilitate the adjustment of a vertical air blowing direction. The present invention further relates to an in-vehicle air output system comprising the air outlet device. According to the air outlet device of the present invention, the horizontal air guide member or the vertical air guide member is always driven by only one electric motor, and during the movement of the vertical air guide member, the horizontal air guide member remains stationary, thereby reducing the rotation amplitude of the electric motor and improving the rotation efficiency of the electric motor.

The adjustment structure comprises: lower slide rails (16) that are arranged opposite to each other and fixedly mounted on a vehicle body floor; a first upper slide rail (11) and a second upper slide rail (12) that are slidably provided on each of the lower slide rails (16), the second upper slide rail (12) being located at the position close to a seat back (22) of a seat; a first connecting rod (13) that has one end rotatably connected to the first upper slide rail (11) and the other end rotatably connected to the end of a seat framework (21) facing away from the seat back (22); and a second connecting rod (14) that has one end rotatably connected to the second upper slide rail (12) and the other end connected to the end of the seat framework (21) close to the seat back (22). By moving the first upper slide rails (11) back and forth along the lower slide rails (16), the first connecting rods (13) are driven to rotate, and the seat framework (21) is inclined, thereby changing an included angle between the seat framework (21) and the vehicle body floor.

Abstract

Provided is a control assembly (3) for a seat belt retractor, the control assembly comprising a first electric motor (31), a second electric motor (32), a control module (33), a third electric motor (34) and a retractor (35), wherein the control module (33) is separately connected to the first electric motor (31), the second electric motor (32) and the third electric motor (34), and collects rotation signals of the first electric motor (31) and the second electric motor (32) and outputs a compensation signal to the third electric motor (34); the rotation of the first electric motor (31) and the rotation of the second electric motor (32) are both related to the angle of the retractor (35); and the third electric motor (34) is connected to the retractor (35) and directly compensates the angle of the retractor (35). Further provided is a vehicle seat comprising the control assembly (3). The control module (33) collects the signals of the first electric motor (31) and the second electric motor (32) and outputs the compensation signal in real time and transmits same to the third electric motor (34), and then the third electric motor (34) adjusts the retractor (35) accordingly, so that a seat belt can be normally used during the full adjustment process of the vehicle seat.
