Problems solved by technology

The current car seat frame is mainly composed of iron components. Due to the high density of iron, the weight of the seat is heavy. Even if high-strength light and thin steel plates are used, it is difficult to reduce the weight significantly. Leading to a substantial increase in mold costs
Therefore, there is the problem and deficiency that it is difficult to effectively reduce the weight of the seat in the existing technology

Embodiment Construction

[0023] The present invention will be further described below in combination with specific embodiments and accompanying drawings.

[0024] Such as figure 1 Shown: an automobile seat frame widely used in aluminum alloy castings, including a seat cushion assembly 1 and a backrest assembly 3 interconnected by backrest bolts 2 .

[0025] Such as figure 2 , 3 As shown: the seat cushion assembly 1 includes an upper seat frame assembly 13 and a lower seat frame assembly 15 installed up and down by using step bolts 14, and the seat pan assembly 12 is installed on the upper seat frame assembly 13 through the first rivet 11 , The riser 17 and the riser handle 19 are installed on one side of the seat frame assembly 13 by using the riser handle bolts. A spring support 4 is provided between the seat pan assembly 12 and the upper seat frame assembly 13 to fix the spring and prevent it from shifting. For the safety and stability of the structure, the inner side of the riser 17 installed ...

Abstract

The invention belongs to the technical field of automotive seats, and discloses an automotive seat framework widely adopting aluminum alloy castings. The automotive seat framework comprises a seat cushion assembly and a backrest assembly which are interconnected. The seat cushion assembly comprises an upper seat frame assembly and a lower seat frame assembly which are vertically overlaid. A sitting basin assembly is arranged on the upper seat frame assembly. A raiser and a raiser handle are arranged at one side of the upper seat frame assembly. A spring bracket is arranged between the sittingbasin assembly and the upper seat frame assembly. The automotive seat framework is simple in structure. The automotive seat framework adopts a seat framework which is mostly composed of the aluminum alloy castings. The density of aluminum is much lower than the density of ferric, so the automotive seat framework is more than 20% lighter, and the seat framework produced with aluminum has obvious advantages over a framework produced with pure iron. Most parts of the automotive seat framework are of integrated structures, so that structural strength and impact-resistance are greatly improved.

Description

technical field [0001] The invention belongs to the technical field of automobile seats, and relates to an automobile seat frame, in particular to an automobile seat frame widely adopting aluminum alloy castings. Background technique [0002] In order to save energy, reduce emissions, and improve resource utilization, the current automobile emphasizes lightweight design, and puts forward lightweight requirements for all parts of the car. Seats are a part of the car that accounts for a large proportion of mass, and weight reduction is imperative. The current car seat frame is mainly composed of iron components. Due to the high density of iron, the weight of the seat is heavy. Even if high-strength light and thin steel plates are used, it is difficult to reduce the weight significantly. Lead to a substantial increase in mold costs. Therefore, there is the problem and deficiency that it is difficult to effectively reduce the weight of the seat in the prior art. Contents of t...
