Longitudinal Seats for Rail Vehicles

Abstract

The invention provides a longitudinal seat of a rail car. The longitudinal seat of the rail car comprises a seat surface and a framework; the framework comprises a plurality of brackets which are independent from each other; mounting connectors which are connected with a car body are formed in the rear ends of the brackets; hooks for hooking the rear part of the framework are arranged at the upper parts of the brackets; adjusting sheets equipped with transverse adjusting holes are horizontally arranged on the brackets; a framework profile equipped with T-shaped slots is arranged on the framework and above the adjusting sheets; sliding slots are positioned in the T-shaped slots; studs of the bolts pass through the adjusting holes to transversely and lengthways adjustably fix the seat surface on the framework. According to the longitudinal seat of the rail car, the traditional seat framework and the seat mounting seat are combined into one part, the surface framework is divided into plurality of independent brackets, and the mechanisms which can be transversely and lengthways adjusted and positioned are arranged between the brackets and the surface framework. The seat is flexible and convenient to mount; the shortages of the existing structure are avoided; the difficulty and cost of manufacturing are reduced; follow-up maintenance and repair of a vehicle are convenient.

Description

technical field [0001] The invention relates to a rail vehicle longitudinal seat, which belongs to the technical field of rail vehicle interior structures. Background technique [0002] At present, most of the longitudinal seats on the subway vehicles are composed of three parts (such as the Chinese invention patent application CN 103101550 A): the seat surface, the seat frame, and the seat mounting seat. The installation method of this seat is Before installing the wall panels, the seat mounts are pre-installed on the car body. After the wall panels are installed, the seat mounts inside cannot be adjusted. Once a problem occurs, all parts on the side wall must be removed to replace or adjust the inside.
