Embodiment 1

[0023] Example one, as figure 1 and figure 2 The shown anti-submarine-slip structure for a rear seat of an automobile includes an automobile chassis 1. The automobile chassis 1 includes a rear seat area 2, and a car seat 3 is provided above the rear seat area 2. An anti-submarine sliding member 4 is arranged above, a groove is formed on the car seat 3, and the anti-submarine sliding member 4 extends into the groove and the two can be tightly connected together.

[0024] The cross-section of the anti-submarine sliding member 4 is a zigzag structure, which is integrally stamped and formed from sheet metal. , the left and right directions of the anti-submarine sliding member 4 form a channel that runs through the anti-submarine sliding member 4. The hollow setting of the channel makes the support strength of the structure stronger than that of the car seat 3, preventing the structure from being easily in a submerged state. The deformation also satisfies that the structural per...

Embodiment 2

[0026] Example two, as image 3 , Figure 4 and Figure 5 The ordinary car shown has an auxiliary seat 23. In order to achieve a certain safety for the person sitting on the auxiliary seat 23, it is necessary to carry out an anti-submarine sliding design for the auxiliary seat 23. The anti-submarine sliding structure of the auxiliary seat 23 is specific. As follows, below the auxiliary seat 23 is an auxiliary seat area 22 included in the rear seat area 2 , an auxiliary anti-slip piece 5 is provided above the auxiliary seat area 22 , and the auxiliary seat 23 is provided with an auxiliary anti-slip piece 5 . The groove cooperates with the auxiliary anti-submarine sliding member 5 , so that the auxiliary anti-submarine sliding member 5 can extend into the auxiliary seat 23 during placement.

[0027] As one of the structures of the auxiliary anti-submarine-slip member 5 in the second embodiment, the auxiliary anti-submarine-slip member 5 includes an auxiliary support surface 51...

Embodiment 3

[0030] In the third embodiment, on the basis of the first embodiment, the first support surface 43 is designed as an arc surface, which matches the bending state of the knee joint and supports the thigh. When the seated person on the first support surface 43 is normally seated, the first support surface 43 is a flat plane. When the vehicle produces an instantaneous movement with excessive relative acceleration, the seated person will dive, and the dive behavior will The anti-submarine sliding member 4 can be deformed so that the seated person is comfortable.

Abstract

The invention relates to a latent sliding prevention structure of a rear seat of an automobile, and belongs to the field of safety design of automobile collision. The latent sliding prevention structure comprises an automobile chassis and a rear seat region included in the automobile chassis, wherein automobile seats are arranged above the place outside the rear seat region; a latent sliding prevention element extending into the automobile seats is arranged on the upper side in the rear seat region; and the latent sliding prevention element comprises a second supporting surface welded to the rear seat region, an inclined supporting surface welded to the rear seat region and a first supporting surface for fixedly connecting the second supporting surface to the inclined supporting surface. By the adoption of the scheme, massaging can be realized when the automobile runs, and some simple optimizations for the automobile body structure are carried out; and the latent sliding prevention structure is additionally arranged on a base plate, so that the problem that a passenger slides downwards and moves forwards when the automobile has head-on collision is solved.

Description

technical field [0001] The invention relates to the field of automobile collision safety design, in particular to an anti-submarine-slip structure for preventing rear passengers from slipping off the seat during a frontal or rear collision of an automobile. Background technique [0002] With the continuous improvement of automobile safety performance, there are more and more requirements for the design of the frame structure, including the anti-skid performance requirements for rear passengers. When the vehicle is subjected to a frontal collision or sudden braking, the The sharp lowering makes the occupant's buttocks move forward and downward due to inertial energy, that is, the phenomenon of diving or slippage occurs, which may cause injury to the occupant. Since the existing car only has the anti-slip design for the front seat, the anti-slip design is only applied to the front seat because the bracket of the front seat is separated from the frame, and the rear seat is dire...
