Seat with a seat plate of adjustable inclination and a backrest of adjustable inclination

A seat, particularly an office chair, comprising a seat plate of adjustable inclination arranged on a seat carrier, and a backrest of adjustable inclination, characterised in that a first gas spring acts between the seat plate and seat carrier to adjust the inclination of the seat plate and a second spring acts between the seat carrier and backrest to adjust the backrest inclination, that the valve actuating pins of the gas springs are provided at the ends associated with the seat carrier and are oppositely disposed, preferably in V formation, and that a horizontal adjusting lever extending transversely to the valve actuating pin arrangement is mounted on the seat carrier to pivot vertically and horizontally about a common pivot point disposed beyond the straight connecting line between the valve actuating pins, and that two control arms on the seat carrier are movable in a scissor-like manner in a vertical plane containing the valve pin arrangement, the adjusting lever engaging between and co-operating with the control arms which co-operate with the valve actuating pins.
