Description

Technical Field

[0001] This utility model belongs to the field of automotive seat technology and relates to a belt guide structure for automotive seats. Background Technology

[0002] Currently, car seats have many straps, such as seat belts used to protect occupants' lives in the event of a collision and pull straps used to unlock the backrest lock. For example, Chinese patent literature discloses a rear seat seat belt restraint system and automobile (authorization announcement number: CN209987889U), including a rear seat and a seat belt assembly installed on the rear seat. The seat belt assembly includes a guide block, a retractor, a webbing, a fixing device, and a locking tongue. The guide block has a guide hole and a mounting groove. One end of the webbing is wound inside the retractor, and the other end of the webbing passes through the guide hole and is fixed to the fixing device. The locking tongue is movably installed on the webbing.

[0003] The rear seat belt restraint system has the following shortcomings during use: the guide block itself is large and made of plastic, which makes it inconsistent with the leather seat. At the same time, the guide hole is located at the top of the guide block and the rear seat back, which causes the seat belt to bend when pulled, resulting in a jerky and difficult pull. In addition, the rear seat belt restraint system does not have a structure for storing the belt, which makes the belt easy to place and difficult to find. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a belt guide structure for automotive seats. The technical problem this invention aims to solve is addressing the issues of incompatibility between existing seat belt guide structures and seats, awkward use, and inability to be used for belt storage.

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

[0006] A guide structure for a car seat includes a backrest frame and a foam and a cover sequentially covering the backrest frame. A backrest lock is installed on the backrest frame, and a pull strap for unlocking is connected to the backrest lock. The guide structure is characterized by including a fixing seat fixed to the backrest frame, the fixing seat having a clearance hole and a cover plate located outside the cover plate that closes the clearance hole. The cover plate has a guide ring and a guide sleeve, both vertically arranged. The guide ring is located at the top of the cover plate and has a break, the guide sleeve is located at the bottom of the cover plate and inserted into the clearance hole, and the pull strap is located inside the guide sleeve with its top extending out of the cover plate.

[0007] This seat belt guide structure has only one cover plate exposed outside the seat cover. The small size of the cover plate allows for better integration with the seat. The guide ring for guiding the seat belt is vertically positioned at the top of the cover plate, ensuring that the seat belt passing through the guide ring has no obvious bends and pulls more smoothly. This solves the problems of incompatibility and awkward use of existing seat belt guide structures. In addition, the opening on the guide ring makes it easy for the seat belt to be inserted into the guide ring from the opening position. The pull strap is located in the guide sleeve of the cover plate, and the top of the pull strap extends out of the guide sleeve. Users can unlock the seat back and recline it forward with just a gentle pull of the pull strap, thus solving the problem of pull strap storage and making it more convenient for users to unlock the seat back. This also makes the seat belt guide structure of this car seat more versatile.

[0008] In the aforementioned guide structure for a car seat, the guide ring and guide sleeve are arranged side by side. The cover plate has a plug-in post located below the guide ring, and the fixing seat has a plug hole. The plug-in post is inserted into the plug hole. The bottom of the guide sleeve has an elastic claw, which can engage with the wall of the clearance hole. This enhances the stability of the connection between the cover plate and the fixing seat, facilitates disassembly and assembly, and prevents the cover plate from shaking during use.

[0009] In the aforementioned belt guide structure for a car seat, the cover plate has a downwardly recessed groove. The cover plate is connected to the mounting base by several screws located within the recessed groove. A decorative cover for concealing the recessed groove is also detachably connected to the cover plate. The decorative cover and the guide ring are arranged adjacent to each other, and the edge of the decorative cover has a notch. The screws further enhance the stability of the connection between the cover plate and the mounting base. The decorative cover conceals the screws, allowing them to be hidden within the cover plate, thus enabling the belt guide structure to better integrate with the seat. Simultaneously, the notch allows the user to easily remove the decorative cover using a flathead tool, making the installation and removal of the decorative cover more convenient.

[0010] In the aforementioned guide structure for a car seat, the top of the fixing seat has a downwardly recessed annular step with several protrusions. The seat cover has mounting holes, and the cover plate presses and positions the portion of the seat cover located at the edge of the mounting holes against the protrusions. This allows the cover plate to press the seat cover firmly, preventing noticeable wrinkles at the connection between the cover plate and the seat cover, thus enabling the cover plate to better integrate with the seat.

[0011] In the aforementioned guide structure for a car seat belt, the top inner wall of the guide ring has a raised ridge, the lower surface of which is arc-shaped, and the bottom outer wall of the guide ring has an inwardly recessed groove. The arc-shaped raised ridge on the lower surface enhances the structural strength of the guide ring and better guides the seat belt located below the raised ridge, making the pulling of the seat belt through the guide ring smoother.

[0012] Compared with existing technologies, the advantages of the belt guide structure of this car seat are as follows: Only one cover plate is exposed outside the seat cover. The small size of the cover plate allows for better integration with the seat. The guide ring for guiding the seat belt is vertically positioned at the top of the cover plate, making the seat belt pull smoother as it passes through the guide ring. This solves the problems of incompatibility and awkward use of existing belt guide structures with the seat. Furthermore, the pull strap is located inside the guide sleeve of the cover plate, with its top extending beyond the sleeve. Users can easily unlock the seat back and recline it forward by simply pulling the strap, thus solving the problem of strap storage and facilitating the user's operation of unlocking the seat back. This also makes the belt guide structure of this car seat more versatile in function. Attached Figure Description
