A seat front mounting bracket and a car

Abstract

The invention discloses a front mounting bracket of a seat. The front mounting bracket comprises a mounting piece and a lateral supporting piece. The mounting piece comprises a supporting plate, a slide rail mounting plate and a beam mounting plate, wherein the slide rail mounting plate and the beam mounting plate are fixed to the two ends of the supporting plate respectively. The slide rail mounting plate and the beam mounting plate are respectively provided with mounting holes. The slide rail mounting plate is fixed to a seat slide rail through bolts. The beam mounting plate is fixed to a seat beam through bolts. The lateral supporting piece is connected to the slide rail mounting plate and arranged opposite to the supporting plate. The lateral supporting piece, the supporting plate and the slide rail mounting plate form an open cavity of a groove structure. The front mounting bracket can reduce deformation of a seat basin in the Y-direction and the Z-direction, is high in bending resistance and improves the safety performance of the seat in a high-speed collision. In addition, when the seat is mounted on different platforms, only the Z-direction design height of the front mounting bracket needs to be changed, and there is no need to change the structures of the seat slide rail and the parts above the seat slide rail. The invention further discloses an automobile comprising the front mounting bracket of the seat.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to a seat front mounting bracket and an automobile. Background technique [0002] With the continuous development of the domestic automobile market, consumers are paying more and more attention to and understanding the passive safety of automobiles. The frontal 100% overlapping rigid barrier crash test and the frontal 40% overlapping deformable barrier crash test are important inspection contents in the crash performance. These two experimental conditions reflect the impact on the vehicle under a combination of qualitative and quantitative conditions. The evaluation of safety reflects the vehicle's ability to protect the occupants to a certain extent. [0003] In the above two experimental conditions, when the seat belt is buckled on the seat, since the seat belt is subjected to the inertial force of the driver or passenger, the seat pan will bear the force in the Y and Z direct...

AI Technical Summary

Problems solved by technology

Since the Z-shaped seat mounting bracket has only one support plate, it is prone to tilt deformation in the Y direction and has poor bending resistance

When the installation bracket space is small, the design height of the Z-shaped structure cannot meet the strength requirements

When seat mounting holes and seat lower rails are not in the same longitudinal direction, changes to seat manufacturing molds and welding tooling are also required, thus increasing manufacturing costs
