Description

Technical Field

[0001] This utility model belongs to the field of seat installation technology, specifically relating to a fixing clamp for a seat back frame. Background Technology

[0002] The car seat backrest frame is a key structural component of the seat assembly. It supports the human back, ensuring passengers maintain a correct sitting posture and providing upper body support. In the event of a collision, the backrest frame absorbs impact energy, protecting passengers from injury. Especially in rear-end collisions, the backrest frame plays a crucial role in protecting occupants and preventing injuries during traffic accidents. Backrest frames are typically equipped with an adjuster, allowing the backrest to be adjusted within a certain range to meet the seating needs of different passengers.

[0003] The installation of car seat backrest frames requires the use of welding machines and bolt fastening tools to assemble the parts. Because car seat backrest frames are irregularly shaped, misalignment is inevitable during the assembly of parts, resulting in parts not meeting assembly requirements, affecting product use and overall quality.

[0004] Therefore, this utility model provides a fixing clamp for a seat back frame to solve the problems mentioned in the background art. Utility Model Content

[0005] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a fixing clamp for a seat back frame, which is used to fix the seat back during the installation process, and can also adjust the installation angle of the seat back to improve the installation efficiency.

[0006] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0007] A fixing clamp for a seat back frame includes a back frame, a fixing device, and an adjustable fixing base. The fixing device is disposed on the adjustable fixing base and is used to clamp and fix the back frame.

[0008] The fixing device includes multiple sets of frame fixing fixtures, multiple fixing cylinders, a base plate, multiple guide rails, multiple baffles, and multiple positioning columns. The base plate is fixedly connected to an adjustable fixing base. The guide rails are laid flat and fixed on the base plate. The multiple sets of frame fixing fixtures are slidably connected to the guide rails. One baffle is provided as a side wall of the frame fixing fixture. The multiple positioning columns are connected to the side wall of the baffle. The fixing cylinders pass through the baffles and are connected to the frame fixing fixture.

[0009] The bottom of the backrest frame has multiple positioning holes that mate with the positioning posts.

[0010] Furthermore, the frame fixing fixture, fixing cylinder, guide rail, and baffle are each provided in at least two sets, and the positioning pins 8 are provided in at least four sets. This structural design, where one frame fixing fixture, fixing cylinder, baffle, and two positioning pins form one end of the fixing device, and the other end consists of identical components arranged opposite each other, allows for clamping and fixing of the back-to-back frame with fewer components, saving production costs.

[0011] Furthermore, the gap between the backrest frame and the frame fixing fixture shall not exceed 0.5mm.

[0012] Further specified, the diameter of the positioning post is not less than 7.5 mm, and the diameter of the positioning hole is not less than 8.5 mm.

[0013] Further, it also includes a safety cover, which is used to cover the fixed cylinder 4, and the gap between the top of the safety cover and the backrest frame is not less than 77mm.

[0014] Further, it also includes an angle adjustment mechanism, the bottom of which is fixedly connected to an adjustable fixed base, and the top of which is fixedly connected to a base plate. The angle adjustment range of the angle adjustment mechanism is 45° to 180° in the horizontal direction. This structural design facilitates the adjustment of the flip angle of the backrest frame, thereby facilitating the installation of other components.

[0015] Further specifying, the length of the base plate is in the range of 640mm to 772mm.

[0016] The beneficial effects of this utility model are:

[0017] This utility model mainly uses a frame fixing fixture, an adjustable fixing base, a fixing cylinder, and an angle adjustment mechanism to fix both ends of the car seat backrest through multiple sets of frame fixing fixtures, positioning columns, and positioning holes. Then, the adjustable fixing base and angle adjustment mechanism are used to adjust the flip angle of the backrest frame. This not only facilitates the installation of other components but also improves installation efficiency. At the same time, it ensures that subsequent construction work such as welding, bolting, cutting, grinding, and repair of the backrest frame can be carried out efficiently.
