Technical Field
The invention relates to the technical field of automobile seat parts, in particular to a seat frame side plate and a seat framework comprising the seat frame side plate.
Background
When a vehicle is running, drivers and passengers are easily injured in case of collision (including front collision and rear collision), wherein the front collision is called front-row trunk dynamic collision, and the rear collision is called rear whiplash dynamic collision. Two mounting holes of the lower connecting plate and the seat frame side plate of the traditional angle adjuster are round holes, so that the lower connecting plate and the seat frame side plate cannot play a role in collision energy absorption in a dynamic collision accident, and drivers and passengers are easily injured. In order to reduce the damage caused by the car collision, car manufacturers have developed seats capable of absorbing energy dynamically, for example, an energy absorbing plate is added on the lower connecting plate of the angle adjuster, or various weakening holes and buffer structures are added on the lower connecting plate of the angle adjuster.
For the design that the energy absorption plate is additionally arranged on the lower connection part of the angle adjuster, the number of parts is increased, and the energy absorption plate needs to be installed and fixed, so that the manufacturing and installation are complex; meanwhile, the additionally arranged energy absorption plate easily causes frictional abnormal sound with the lower connecting plate of the angle adjuster in the normal running process. The design that the weakening hole and the buffering structure are additionally arranged on the lower connecting plate of the angle adjuster enables the stamping process of the lower connecting plate of the angle adjuster to be complex, and meanwhile, after the weakening hole and the buffering structure are additionally arranged, the thickness of the lower connecting plate needs to be increased to ensure the overall strength, so that the weight is correspondingly increased, and the lightweight design of products is influenced.
