Side, the chair legs legs and feet are provided with roller, and the brake block is located on roller, and described brake cable one end is located on seat support liner plate,
The other end is located on brake block.
The invention has the beneficial effects as follows, automatic brake functions being achieved on movable rotary seat, compensate for current city
Do not possess self-stopping design defect after the upper band seat with rollers movement of field, safety in utilization is higher.The present invention passes through mechanical type
Braking principle, simple structure, braking reflection is sensitive and is difficult failure, and the braking of safety opposing electronic is higher.As old man or child
During using common seat with rollers, when layback is leaned on, seat support is unlucky, and easily generation seat freely slides backward situation, old man and child
It is susceptible to collide with or falls injury.When old man or child are using seat with rollers of the present invention, as this seat is with after the chair back
Incline automatic brake functions, even if old man or child's layback lean on seat back, seat also will not backward slidably, it is to avoid receives
Wound.
