Description

Technical Field

[0001] The utility model relates to the technical field of automobile seats, in particular to a crossbeam assembly for fixing seats. Background Art

[0002] The car seat mounting crossbeam assembly is a major component of the car body and a key force transmission component in the side collision of the car. It must have good strength and rigidity so that the car can effectively transmit the force when it is hit. In the side collision condition, if its structural strength is insufficient, the collision buffer area of ​​the car body will be small, the side of the collision car body will be greatly deformed, and the intrusion of the car body and the door will cause serious injuries to the occupants in the car.

[0003] Existing automobile seats are connected and fixed to mounting holes on a crossbeam assembly by bolts. However, the existing crossbeam assembly is generally a strip crossbeam with a hollow or non-closed cross-section. The design of the hollow or non-closed cross-section usually reduces the cross-sectional area of ​​the crossbeam, which reduces the rigidity and strength requirements of the crossbeam to a certain extent, resulting in the seat crossbeam being more easily deformed when impacted or receiving forces transmitted by other structures, thereby reducing the safety of the seat.
