Embedded clamping spring for automobile seat armrest

Abstract

The invention provides an embedded clamping spring for an automobile seat armrest. A clamping spring body of the embedded clamping spring for the automobile seat armrest is a closed-packed structure which is made of winding square metal materials sticking to each other; the integral height of the clamping spring body is 25.3-25.5 mm; the internal diameter of the clamping spring body is 28.5-28.6 mm; ends of the two ends of the clamping spring body are bent outwards for 90 degrees; the length from the end of one end of the clamping spring body after being bent to the center of the clamping spring body is 37.5-38.5 mm; and the length from the end of the other end of the clamping spring body after being bent to the center of the clamping spring body is 30.5-31.5 mm. When the clamping spring is in use after being mounted, the armrest adjustment and locating can be made accurate and reliable through the square materials and the scientific and reasonable structure.

Description

technical field [0001] The invention relates to a component used in the armrest of an automobile seat, in particular to a built-in circlip in the armrest of an automobile seat. Background technique [0002] The armrest of the car seat is adjusted at the same time as the inclination angle of the seat back is adjusted. When adjusting the armrest, one end of the armrest is first lifted up. After the backrest is adjusted and positioned, the armrest is lowered to position it at the same time. And the positioning is realized by the built-in circlip. When the armrest is lifted up, the circlip is driven to loosen the shaft of the armrest. After the armrest is dropped, the circlip hugs the shaft to fix it and position it. The traditional built-in circlip is circular. It is made of metal material, and its circular structure has a circular outer peripheral surface in contact with the shaft. The overall area of ​​the inner diameter of the tightly hugging shaft is limited, resulting in l...

The traditional built-in circlip is circular. It is made of metal material, and its circular structure has a circular outer peripheral surface in contact with the shaft. The overall area of ​​the inner diameter of the tightly hugging shaft is limited, resulting in low friction. In continuous use, it is prone to poor sensitivity and inaccuracy. positioning phenomenon
