Description

Technical Field

[0001] This utility model belongs to the field of automotive parts technology and relates to a seat belt retractor fixing bracket. Background Technology

[0002] The seat belt retractor mounting bracket is a fixed bracket used to install the seat belt retractor in the seat belt system. The mounting bracket is fixed to the vehicle body and is an important component of the seat belt.

[0003] Fixed brackets generally consist of a frame and a connecting bracket, both of which have mounting holes for fixing to the vehicle body. To ensure the connection strength between the connecting bracket and the frame, it is currently common to use two rivets for fixing. For example, a seat belt bracket structure disclosed in Chinese patent literature [Authorization Announcement No. CN203391728U] and a rear seat belt retractor for automobiles [Authorization Announcement No. CN201736945U] both use two rivets for fixing. The two rivets need to be installed to connect the two riveted parts. The two rivets need to be placed in place before riveting, which has low assembly efficiency. At the same time, the rivets need to be purchased, which increases the cost. There is also a risk of missing rivets during installation. Utility Model Content

[0004] The purpose of this utility model is to address the aforementioned problems in the existing technology by proposing a seat belt retractor fixing bracket. The technical problem solved by this utility model is to improve assembly efficiency.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A seatbelt retractor fixing bracket includes a frame and a connecting frame. The frame includes a fixed plate and two side plates located on both sides of the fixed plate. The connecting frame is located on the upper side of the two side plates. The side plates are characterized by having a first hook and a second hook on their upper sides, the first hook and the second hook being opposite to each other and both capable of deformation under pressure. The connecting frame has two limiting slots along its edge and two limiting holes. The first hook of the side plate engages in the limiting slot and deforms to press against the connecting frame, while the second hook of the side plate passes through the limiting hole and deforms to press against the connecting frame.

[0007] The seatbelt retractor is installed in the frame, which is mounted on the vehicle body via a fixing plate and a connecting bracket; the connecting bracket and the frame are secured together by a first and a second hook on the side plate.

[0008] There is no need to assemble two rivets for connection. When fixing, simply insert the first hook into the limiting slot, pass the second hook through the limiting hole, and then use riveting to deform and press the first and second hooks onto the connecting frame to fix the connecting frame to the frame.

[0009] In the aforementioned seat belt retractor fixing bracket, the first hook is L-shaped, including a connecting part connected to the frame and a bent hook part. The hook part is bent toward the second hook side, the connecting part is inserted into the limiting groove, the hook part is disposed opposite to the connecting frame, and the hook part is bent and deformed toward the connecting frame side after being pressed and pressed onto the connecting frame.

[0010] In the aforementioned seat belt retractor fixing bracket, the thickness of the connecting part is the same as the width of the limiting groove.

[0011] In the aforementioned seatbelt retractor fixing bracket, a recess is provided on the upper side of the side plate, directly opposite the hook portion. When the hook portion is riveted and pressed onto the connecting frame, the contact point between the connecting frame and the hook portion will also deform under force. The deformed part will engage with the recess, and the hook portion will embed into the deformed part of the connecting frame, which in turn will embed into the recess, making the connection between the connecting frame and the side plate more secure.

[0012] In the aforementioned seatbelt retractor fixing bracket, the second hook includes a connecting part two connected to the frame and a hook part two inclined towards the first hook side. The connecting part two passes through a limiting hole. After being pressed, the hook part two bends and deforms towards the connecting frame side and is pressed tightly onto the connecting frame. The length of the limiting hole is greater than the bottom length of the connecting part two. This structure, with the second hook cooperating with the first hook, facilitates the installation of the connecting frame.

[0013] In the aforementioned seatbelt retractor fixing bracket, the width of the second connecting part gradually decreases from the bottom upwards. This structure ensures the connection strength between the second connecting part and the side plate, while also making the second hook part easy to be riveted and deformed.

[0014] In the aforementioned seat belt retractor fixing bracket, the thickness of the second connecting part is the same as the width of the limiting hole.

[0015] In the aforementioned seatbelt retractor fixing bracket, a recessed opening is provided on the upper side of the side plate, directly opposite the second hook portion. When the second hook portion is riveted and pressed onto the connecting frame, the connecting frame will also deform under force at the contact point with the second hook portion. The deformed part will engage with the recessed opening, and the second hook portion will embed into the deformed part of the connecting frame, which in turn will embed into the recessed opening, making the connection between the connecting frame and the side plate more secure.

[0016] In the aforementioned seat belt retractor fixing bracket, the connecting frame includes a connecting plate portion and a fixing plate portion, the connecting plate portion and the fixing plate portion are arranged vertically, the limiting slot and the limiting hole are provided on the connecting plate portion, the fixing plate portion has a first mounting hole and a second mounting hole, and a reinforcing protrusion is provided between the connecting plate portion and the fixing plate portion.

[0017] Compared with existing technologies, this seat belt retractor fixing bracket has the advantages of reducing material costs and assembly complexity, improving assembly efficiency and product quality, and achieving the goal of lightweighting while ensuring product performance.
