VARIABLE BACK ADJUSTOR FOR CHAIRS |
摘要 |
An adjustor for chairs with tilting backs and the like, comprises a threaded spindle connected with the chair back, and a gear wheel threadedly mounted on the spindle. The gear wheel is retained in a housing attached to a relatively stationary portion of the chair, such that when the chair back is tilted, the spindle rotates the gear wheel in the housing. A pawl is shifted into and out of engagement with the gear wheel to selectively lock the chair back in a wide variety of different angular positions. |
