Description

Technical Field

[0001] The utility model relates to the technical field of vehicle safety belts, in particular to a vehicle B-pillar with an adjustable safety belt slide plate height. Background Art

[0002] Seat belts are one of the important parts of a vehicle to ensure the safety of passengers. Front-seat passengers need to wear seat belts all the time. In order to make seat belts have better wrapping for passengers of different body shapes and heights, so as to better restrain the passengers' bodies in the event of a vehicle collision, vehicles are generally equipped with seat belt height adjustment devices. The seat belt height adjustment device can be used to adjust the height of the seat belt to make it suitable for passengers of different body shapes and heights.

[0003] The seat belt slide plate installed on the B-pillar trim of the car is mostly a mechanical structure that needs to be manually adjusted. The height adjustment of the seat belt slide plate is mostly four height positions, and it needs to be manually unlocked and then manually adjusted by sliding the seat belt slide plate up and down. Since the height position of the seat belt slide plate is not steplessly adjustable, the seat belt slide plate of this structure cannot adapt to drivers or passengers of any different body shapes. Since the occupants in the car usually find that the height of the seat belt is not appropriate after sitting in the seat and then adjust the height, they need to stretch their hands behind their backs when adjusting, which is very inconvenient to operate and reduces the comfort of the ride. To this end, the utility model proposes a car B-pillar with an adjustable seat belt slide plate height, in order to solve the above technical problems. Summary of the invention

[0004] The purpose of the utility model is to overcome the defects in the prior art and provide a car B-pillar with an adjustable seat belt slide height. The height of the seat belt slide is adjusted by a motor drive to achieve stepless adjustment of the seat belt height, which can adapt to drivers and passengers of different body shapes and provide more position options within a specified height range, thereby ensuring that the seat belt is in the position where the driver and passenger feel most comfortable. The seat belt height adjustment realizes semi-automatic control and is easy to operate, which significantly improves the riding experience of the driver and passenger. The overall structural design is simple, the preparation and implementation feasibility is high, and the practicability is strong.

[0005] To achieve the above-mentioned purpose, the technical solution of the utility model is to design a car B-pillar with an adjustable seat belt slide height, comprising a B-pillar body, a seat belt slide and a drive motor, the B-pillar body is provided with a window, the left and right sides of the rear side surface of the B-pillar body are respectively provided with slide grooves with openings horizontally facing the inner side thereof, the seat belt slide is located on the rear side of the B-pillar body and fits in correspondence with the window, the left edge of the seat belt slide is slidably inserted into the inside of the slide groove on the left side of the B-pillar body, and the right edge of the seat belt slide is slidably inserted into the inside of the slide groove on the right side of the B-pillar body, the left edge or the right edge of the seat belt slide is also provided with a rack distributed in the longitudinal direction, and the output shaft of the drive motor is provided with a gear meshing with the teeth on the rack.

The upper limit block limits the uppermost point of the seat belt slide, and the lower limit block limits the lowermost point of the seat belt slide, thereby preventing the seat belt slide from derailing during the sliding adjustment process and ensuring the safety of the seat belt height adjustment.

[0008] A further preferred technical solution is that the left and right side edges of the rear side of the seat belt slide are respectively provided with a plurality of longitudinally distributed reinforcing ribs, and the upper ends of the reinforcing ribs on the left and right sides of the rear side of the seat belt slide are respectively provided with protrusions extending toward the inner side of the B-pillar body, and the protrusions and the reinforcing ribs and the rear side of the seat belt slide are enclosed to form the slide groove. The slide groove structure is reasonably simple in design, is easy to form on the rear side of the B-pillar body, and has high feasibility of preparation and implementation.

[0009] A further preferred technical solution is that the teeth are located on a vertical edge of the rack facing the outside of the B-pillar body, and the drive motor is fixedly arranged at the left edge or the right edge of the rear side of the B-pillar body. The drive motor is installed at a reasonable position, and the gear on the output shaft of the drive motor and the rack on the seat belt slide are meshed and matched ingeniously, and the overall structural design is compact and reasonable, and does not take up more installation space.
