Abstract
The invention provides a manual reversing seat for a railway vehicle. The manual reversing seat comprises a supporting bracket 1, an installation rack 2, a backrest 3, a seat cushion 4, a headrest 5, a handrail 6, a foot pedal 7 and a double-rocker reversing mechanism. A handle on the upper part of the backrest is pushed by hand, so the backrest moves and inclines the seat cushion reversely via the double-rocker reversing mechanism to complete reversion of the seat. The weight of the seat cushion and the weight thereon are transferred onto the installation rack and the supporting bracket below the seat cushion via bearing wheels at the two ends of the seat cushion, and are interlocked with the backrest along a slipway on the installation rack. When the seat cushion moves and inclines reversely, a draw plate hinged on the bearing wheel pulls a batten swinging arm to lower or retract a foot pedal crossbeam so as to realize reversing. The seat is comfortable to seat and has a compact structure and convenient manual reversion; the seat not only can adapt to the demand of a high-speed motor train unit, but also can be widely applied to other various railway passenger cars; and not only the manufacturing cost of the seat and the entire vehicle can be reduced greatly, but also the passengers in the vehicle can be increased. Therefore, the manual reversing seat has remarkable economic benefit and very wide market prospect.
