A Variety Of Car Seat Tubes
Dear friend, have you ever seen car seat tubes? And what is a car seat tube?
I believe most of us will be familiar with car seats, but have no idea of the seat tubes, even though we drive cars every day, enjoying the comfort that car seats provided. When people talk about the seat, they normally say that it is leather or knit, and they only pay attention to the surface material. Today, this article introduces the inner soul of the car seat - the seat frame tube, Let's take a look at what's inside the sponge.
When it comes to the seat frame tubes, let's start with the composition of the seat. According to the structure, car seats can be divided into steel frames, foam, masks and plastic parts. Today's main topic is seat frame, seat frame is assembled of steel pipe, steel plate stamping parts, springs and other parts. The following is a seat frame drawing. We can clearly see that there are many steel tube parts on the seat frame, for example,A slide for adjusting the position of the headrest(position 11), And back seat support(position 10), here are also seat cushion steel tube (position 6) etc. Some of them are round tubes, some are square tubes, some have holes on the tube, or other processing shapes. Then we will summarize the steel tube parts used in the seat tube.
According to the section shapes of steel tubes, they can be classified into three categories: square tube, rectangular tube and circular tube. What we are talking about here is the cross-section shape of steel tubes, please see the picture below:
From the shape of the axis of the steel tube, there are straight tube and bending tube two kinds.
In terms of processing types, there are punching, stamping, welding, shrinkage, flaring and so on.
Generally, the strength requirements of seat tubes in different positions are different, which depends on the requirements of structural strength, generally, they are Q235B, Q355B, Q460B, yield strength from 235MPa to 460MPa, etc.
According to the different wall thickness requirements, seat tube is divided into a cold-rolled steel tube and hot rolled steel tube. Generally, the wall thickness of a cold-rolled steel tube is less than 2.0mm, when the wall thickness is greater than or equal to 2.0mm, a hot-rolled steel tube is more common.
Finally, these steel tubes of different shapes are welded together to form the seat frame, as shown in the drawing above. The seat frame is the support for the interior of the seat and ultimately plays a crucial role in the various functions and comfort of the seat.
That’s all we would like to introduce about seat frames today, I believe you have learned a lot of seat frame, if you want to know more, please visit our website www.cbiesautomotive.com, thank you.
