Description

A kind of skeleton built-in blow molding bus seat

technical field

The utility model relates to the field of bus seats, in particular to a blow-molded bus seat with a built-in skeleton, which belongs to the technical field of bus supporting facilities.

Background technique

With the rapid increase of the urban population, the urban public transport system is also facing new challenges. As a bus closely related to the travel of the urban population, it has attracted more and more attention. The ride comfort requirements of urban buses are getting higher and higher, and the most direct relationship with the ride comfort is the bus seat. At present, the widely used bus seat mainly adopts the structure that the frame is fixedly connected with the bottom surface of the seat. When the bus collides or brakes suddenly, not only the exposed frame is likely to cause injury to the passengers, but in serious cases, the frame and the seat may be damaged. Therefore, there is a great potential safety hazard.

Utility model content

The technical problem to be solved by the utility model is to propose a blow-molded bus seat with a built-in skeleton that can effectively eliminate potential safety hazards, and also help to improve the shock absorption and comfort of the seat in view of the above shortcomings of the prior art Spend.

In order to solve the above-mentioned technical problems, the technical solution of the utility model is realized in the following way: a blow-molded bus seat with a built-in skeleton, including a headrest, a main body and a skeleton, the main body is a blow-molded hollow structure, and the main body includes a seat back There are two parts with the seat cushion; the two sides of the top of the chair back are respectively provided with cylindrical grooves, and plug-ins are inserted in the cylindrical grooves; the headrest is fixedly connected with the seat back through the plug-ins; the lower end of the bottom of the chair back extends horizontally out of the cushion, There are two through holes on the outer surface of the joint between the back and the seat cushion. The skeleton is inserted into the through holes and fixed in the hollow chair back. The skeleton includes a first support part built into the chair back and a second support part fixedly connected to the seat cushion. .

Like this, through the technical scheme of the utility model, the skeleton is made up of two L-shaped elbows and the C-shaped steel for fixedly connecting the bottom ends of the L-shaped elbows, and the skeleton is fixedly connected to the inside of the seat cushion and the hollow seat back, which plays an important role in bus seats. The fixing function not only increases the shock absorption performance, but also reduces potential safety hazards, and the technical scheme has simple structure, convenient use and simple maintenance.

The technical scheme that the utility model is further limited is:

The aforementioned framework built-in blow-molded bus seat, the framework is composed of at least two L-shaped bends and the C-shaped steel used to fix the bottom of the L-shaped bends. In this way, the strength of the seat is effectively improved and the safety is reduced. Hidden danger.

In the aforementioned frame built-in blow-molded bus seat, the side of the headrest away from the back of the passenger is provided with a rear cover, thus effectively improving the aesthetics of the bus seat.

In the aforementioned frame-built-in blow-molded bus seat, the first support part is longer than the second support part, so the structure is simple and the maintenance is convenient.

In the blow-molded bus seat with a built-in skeleton, the upper surface of the seat cushion is provided with an anti-slip layer, which improves the comfort of passengers.

The beneficial effects of the utility model are: through the technical scheme of the utility model, the skeleton is composed of two L-shaped elbows and a C-shaped steel for fixedly connecting the bottom ends of the L-shaped elbows, and the skeleton is fixedly connected to the inside of the seat cushion and the hollow chair back, The utility model plays a role of fixing the bus seat, not only increases the shock absorption performance, but also reduces potential safety hazards, and the technical scheme has simple structure, convenient use and simple maintenance .
