Description

Drive-by-wire handle structure and seat

Technical Field

The utility model relates to the field of seats, in particular to a wire-controlled handle structure and a seat.

Background

In the era of ergonomics, a comfortable chair inevitably requires adjustment devices with many individual functions, such as a seat elevation adjustment device, a seat front and back adjustment device, a backrest tilt angle swing and adjustment device, and the like, which are common and have practical functions; since these adjustment devices are usually controlled by a pull cord, a plurality of single-function control handles are usually provided under the seat for the user to operate (the device is extended under the seat by the pulling of the pull cord), so that a fully functional chair often has to be provided with a plurality of control handles under the seat for the user to select different function operations.

According to the above structure, although the control handles with different functions are all arranged below the seat for the user to touch and operate at will, too many control handles make the user difficult to remember the correct position, so sometimes the user often needs to leave the seat to find the control handle during adjustment, which deviates from the design intention of arranging the control handle below the seat (the design purpose is to allow the user to sit on the seat and operate directly); in addition, too many control handles are arranged below the seat, so that the appearance is influenced, too much space below the seat is occupied, and many problems need to be considered in the layout; therefore, a wire control handle capable of integrally controlling a plurality of pull wires is needed; at present, a wire control handle capable of controlling a plurality of pull wires is arranged below some seats on the market, but the wire control handle is usually used for controlling 2 or 3 pull wires.
