Abstract
A framework-free blow-molded bus seat is composed of a seat body (1) and a seat leg frame assembly (3). The seat is characterized in that the seat body (1) is connected with the seat leg frame assembly (3) through a seat fixing base (2) buried in the bottom of the seat body (1). The seat is simple in structure and convenient and fast to install. The weight of the seat is effectively reduced. The seat is designed to be free of a steel framework, a traditional technical framework is replaced with the seat fixing base, and therefore seat cost is effectively reduced and the market competitiveness of products is improved. Furthermore, no metal part is exposed from the back of the seat, and therefore secondary injury to passengers can be avoided when vehicle collision occurs and safety of passengers is guaranteed.
Description
Technical field
The present invention relates to a kind of seat, particularly relate to a kind of exoskeletal bus blowing seat.
Background technology
Seat uses extensively in daily life, and existing seat mainly contains sponge seat and injection moulding seat in the market.Wherein the skeleton of sponge seat is steel material, and tensile strength is low, complex manufacturing technology, and overall weight is large, at the bottom of production efficiency, wears no resistance, easily distortion.In order to overcome the defect of above seat, on market, there is again the patent of invention of hollow blow molding armchair, a kind of blow-molded plastic chair patent No. is 20052013018.1, is mainly spliced with Plastic Parts seat cushion sheet and the external steel frame of backrest of hollow.After such seat back, metallic framework exposes, attractive in appearance not; And metallic framework exposes, in the time of collision happens, the metallic framework of seat rear can damage human body.
Summary of the invention
For above-mentioned defect, the object of the present invention is to provide a kind of exoskeletal bus blowing seat, in seat main body blow mold, carry out secondary encapsulate and process and carry out fusion mutually with seat main body and be connected by seat permanent seat good injection mo(u)lding is placed on, after be connected with chair leg support assembly by bolt of rear end plate.
Technical scheme of the present invention is achieved in the following ways: a kind of exoskeletal bus blowing seat, formed by seat main body, chair leg support assembly, it is characterized in that: the seat permanent seat that described seat main body is embedded with by bottom is connected with chair leg support assembly.
Described seat permanent seat is put to carrying out secondary encapsulate in seat main body blow mold and is processed with the material of seat main body and carry out mutual fusion, and seat permanent seat is embedded in seat main body.
In described seat permanent seat, be embedded with builtin-nut.
Described seat main body is provided with multiple reinforcement knots.
The present invention, simple in structure, quick and easy for installation, effectively reduce seat-weight, seat adopts without steel frame design, uses seat permanent seat to substitute traditional technique skeleton, effectively reduces seat cost, has improved product competitiveness in the markets; Chair back, without any exposed metal parts, can not cause passenger's secondary injury in the time of collision happens in addition, ensures its passenger's safety.
