Problems solved by technology

[0002] At present, the seats of subway, high-speed rail and other rail vehicles are generally made of steel frame structure or welded by square aluminum tubes. It will cause damage to the covering outside the frame, and stress concentration may occur at the bend or bend, which will cause the fracture of the seat frame structure
[0003] In addition, the backrest cushions currently used in motor vehicle seats are designed relatively flat on the upper end, which is inconvenient for passengers to sleep on their sides, and the appearance is relatively monotonous. The backrest of the seat will cause damage to the backrest cushion after long-term use, and the current motor vehicle seats The flat and fluffy headrest is used, which cannot effectively protect the passenger's neck, and does not fully consider the factors of man-machine integration. Passengers are prone to fatigue after sitting for a long time, and the existing seats are mostly manufactured by welding process, which is easy to Problems such as virtual welding and welding deformation

Abstract

The invention discloses a backrest frame mechanism which comprises a headrest, a backrest cushion, front cover boards, a rear cover board, a U-shaped frame, a first longitudinal beam and a second longitudinal beam. The front side and the rear side of the U-shaped frame are fixedly connected with the front cover boards and the rear cover board respectively. The backrest cushion is further fixed to the front sides of the front cover boards and sleeved with the U-shaped frame in a penetrating mode. The headrest is arranged at the top of the backrest cushion. The first longitudinal beam and the second longitudinal beam are fixedly arranged at the bottom of the U-shaped frame. By the adoption of the backrest frame mechanism, circular aluminum pipes are bent to form a backrest frame, and the backrest cushion can not be damaged; the headrest is designed to be in an arc shape, the appearance is attractive, and the headrest is better attached to the head and the neck of a passenger; the two sides of the upper end of the backrest cushion protrude, so that the passenger laterally sleeps conveniently.

Description

technical field [0001] The present invention relates to a back frame mechanism, in particular, to a back frame mechanism for a seat of a vehicle. Background technique [0002] At present, the seats of subway, high-speed rail and other rail vehicles are generally made of steel frame structure or welded by square aluminum tubes. It will cause damage to the covering outside the frame, and stress concentration may occur at the bend or bend, which will cause the fracture of the seat frame structure. [0003] In addition, the backrest cushions currently used in motor vehicle seats are designed relatively flat on the upper end, which is inconvenient for passengers to sleep on their sides, and the appearance is relatively monotonous. The backrest of the seat will cause damage to the backrest cushion after long-term use, and the current motor vehicle seats The flat and fluffy headrest is used, which cannot effectively protect the passenger's neck, and does not fully consider the fac...
