Description

Technical Field

[0001] The utility model relates to the technical field of automobile bodies, in particular to a crossbeam installation structure in an automobile seat. Background Art

[0002] The car seat crossbeam is an important structural part of the car body and is used to install the car seat. Figure 1 The existing seat crossbeam structure shown is composed of a seat rear crossbeam and a seat mounting bracket welded together to form a seat rear crossbeam assembly. This welding process will lead to a waste of man-hours. Then the seat rear crossbeam assembly is overlap-welded with the middle channel body. Due to the limitation of the middle channel support plate, spot welding is not possible and only welding can be performed. This requires the addition of a welding station, which not only increases the man-hours, but also has poor anti-corrosion performance and aesthetics. Therefore, a new automobile seat middle crossbeam mounting structure needs to be invented. Utility Model Content
