Height adjustment system and seat anchorage

Abstract

The invention discloses a height adjustment system, which includes a height adjustment motor, a connecting rod assembly, a self-locking assembly and an overturning assembly. After the height adjustment motor drives the connecting rod assembly to move, the connecting rod assembly drives the overturning assembly Flip up and down, the self-locking assembly is installed on the connecting rod assembly, when the height adjustment motor drives the connecting rod assembly, the self-locking assembly unlocks the connecting rod assembly, so that the connecting rod assembly can drive The overturning component is turned upside down; when the overturning component is pushed down by the seat, the overturning component drives the connecting rod component, and the connecting rod component drives the self-locking component to lock with the connecting rod component. The height adjustment system and the seat fixing device in the invention can accurately adjust the seat, facilitate operation, and avoid scratches and deformation of the seat frame.

Description

Height Adjustment System and Seat Fixtures technical field [0001] The present invention relates to the technical field of automobiles, and in particular, to a height adjustment system and a seat fixing device. Background technique Car seats play an important role in the safety and comfort of vehicles, and in the process of vehicle development, The car seat has undergone various evaluations and experimental verifications, and the fixing devices of the car seat are also diversified. With car seats With each passing day, the structure is constantly changing and improving, the conventional car seat fixing device can no longer meet the requirements of fast, universal and convenient automobile Car seat fixation requirements. Therefore, it is necessary to make a new design for the fixing device of the car seat. [0003] There are two forms of current seat fixing tooling: 1. Adopt 4 brackets to fix the 4 mounting holes of the seat with bolts, the fixing process requires th...

AI Technical Summary

Problems solved by technology

[0004] 1. Use 4 brackets to fix the 4 mounting holes of the seat with bolts. The fixing process requires the cooperation of multiple people, the angle of the seat cannot be adjusted accurately, and there is a risk of tools scratching the seat during the fixing process

For the type of seat with a large difference in the height of the front and rear seat legs, this method cannot adjust to the exact position of the seat, and additional pads are needed, which makes the operation complicated and the fixing firmness reduced

[0005] 2. Another way to fix the seat is to press the seat slide rail from outside to inside to fix the seat. Although it can adapt to different seat slide rail widths, it cannot adapt to different seat slide rail lengths. For seats with non-vertical outer walls of slide rails The chair cannot apply pressure, resulting in poor versatility, and the inward pressure slide rail cannot control the force, which may easily cause deformation of the seat frame. In addition, only one side force is fixed in the Y direction, and there is no fixation in the Z direction. The degree of fixation is poor. The middle slide rail will be scratched by the bolt

[0007] 1. Manual fixation cannot achieve automatic adjustment; 2. The operation is complicated and requires the cooperation of multiple people, which wastes man-hours; 3. The position of the seat cannot be adjusted accurately, resulting in deviations in experimental results; 4. There is a risk of scratching the seat with the fixing tool during the fixation process ; 5. It is easy to cause deformation of the seat frame during the fixing process
