Detailed Description

The following describes embodiments of the present invention with reference to the drawings. Numerous details are set forth in the following description in order to provide a thorough understanding of the present invention, but it will be apparent to one skilled in the art that the present invention may be practiced without these details.

Referring to fig. 1 and 2, a vehicle seat for reducing the amount of forward movement of an occupant in a crash situation comprises a seat belt 1, and a backrest 2 and a seat cushion 3 rotatably coupled, the seat belt 1 comprising a webbing 11, a retractor (not shown) and a link; a plurality of guide rings for fixing the woven belt 11 are arranged on the back of the backrest 2; a retractor is arranged below the backrest 1 of the seat cushion 3; one end of the mesh belt 11 is connected with the retractor, and the other end passes through a plurality of guide rings and then obliquely strides in front of the backrest 2 and is connected with the side wall of the cushion 3 through a connecting piece. By analyzing the acting force generated by the safety belt 1 and the passenger in the collision, the guide rings are arranged at different positions of the backrest 2, so that the force transmission path of the mesh belt 11 is changed, and the acting force of the mesh belt 11 is effectively decomposed, so that the pulling-out amount of the mesh belt 11 in the frontal collision is reduced, the forward movement amount of the passenger is effectively reduced, and the life safety of the passenger is ensured.

Referring to fig. 1 and 2, the seat belt is a three-point type fixed structure, the connecting member includes a fixed end piece (not shown), a buckle 121 and a latch 122, and the other end of the webbing 11 is disposed at the right side of the seat cushion 3 through the fixed end piece; the insert buckle 121 is fixedly arranged at the left side of the cushion 3, and the mesh belt 11 is provided with a lock tongue 122 buckled with the insert buckle 121. When a collision accident occurs, the three-point fixing structure is adopted, so that the shoulders and the waist of a passenger can be protected simultaneously, and the safety factor of the seat is effectively improved. The retractor, the eye-splice 121, the lock tongue 122 and the fixed end piece of the seat belt 2 all belong to conventional seat belt components, and those skilled in the art can understand the specific structure and working principle of the existing automobile seat belt, so that detailed description is omitted here.

Referring to fig. 1 and 2, the plurality of guide rings are arranged in a zigzag manner, so that the webbing 11 can form a plurality of inflection points, and the force applied to the webbing 11 under the collision condition is effectively decomposed, thereby reducing the pulling-out amount of the webbing 11 and effectively reducing the forward movement amount of the passenger.

Referring to fig. 1 and 2, as a preferred solution: the plurality of guide rings are arranged in an L shape. Specifically, the guide ring includes a first guide ring 21, a second guide ring 22 and a third guide ring 23, the first guide ring 21 is fixedly disposed at the lower left of the back surface of the backrest 2, the second guide ring 22 is fixedly disposed at the upper left of the back surface of the backrest 2, and the third guide ring 23 is fixedly disposed at the upper right of the back surface of the backrest 2. Through simulation experiments for many times, the guide ring is arranged by adopting the scheme, and reasonable stress decomposition can be carried out on the mesh belt 11, so that under the premise that the mesh belt 11 can be smoothly pulled out when normal working conditions are ensured, the pulling-out amount of the mesh belt 11 impacted under the working conditions of less frontal collision is increased to the maximum extent.

Referring to fig. 1 and 2, more specifically, the first guide ring 21 is a v-21274; the second guide ring 22 is a triangular guide plate obliquely arranged on the back of the backrest 2, and the triangular guide plate is provided with a second guide groove 221 for the woven belt 11 to pass through; the third guide ring 23 is an L-shaped guide plate, one of which has an outer corner surface fixed to the upper right of the back surface of the backrest 2, and the other outer corner surface is provided with a third guide groove 231 for the webbing 11 to pass through. However, the configurations of the first guide ring 21, the second guide ring 22, and the third guide ring 23 are not limited to this, and the mounting positions of the three guide rings may be changed or a guide ring having another configuration may be selected as needed.

Referring to fig. 1 and 2, a stopper 31 is provided at the front end of the seat cushion 3 to abut against the buttocks of the occupant, so that the front end of the seat cushion 3 is inclined forward at an angle. Therefore, the front end of the seat cushion 3 is high, the rear end of the seat cushion is slightly low, and the forward inclination angle of the seat cushion 3 can limit the hip of a passenger to move forwards under the condition of frontal collision so as to improve the restraint force of the seat on the passenger, improve the anti-sinking effect of the seat and effectively prevent the passenger from being bruised. Tests show that the larger the front rake angle of the seat cushion is, the more obvious the blocking effect is, so that the front rake angle of the seat cushion 3 is set to 12 ° in this embodiment on the premise of ensuring the riding comfort.

Referring to fig. 1 and 2, as a preferred solution: the stopper 31 is in the shape of a wedge step, and the stopper 31 is made of ABS material. When a frontal collision occurs, the passenger moves forwards under the action of inertia force, and the step position of the limiting block 31 is just in the stressed zone of the hip of the passenger, so that the energy can be fully absorbed, the forward movement of the passenger is restrained and limited by the reaction force of the limiting block 31, and the life safety of the passenger is ensured.

The above-mentioned be the utility model discloses a concrete implementation way, nevertheless the utility model discloses a design concept is not limited to this, and the ordinary use of this design is right the utility model discloses carry out immaterial change, all should belong to the act of infringement the protection scope of the utility model.
