Abstract
The utility model relates to a light-weight seat cushion turnover device, which comprises a seat framework welding assembly, wherein the seat framework welding assembly is movably connected with a back rest framework welding assembly and a bottom frame welding assembly through irregularly-shaped bolts in sequence, the bottom frame welding assembly is movably connected with a limiting plate through small bolts, and the limiting plate is connected with the back rest framework welding assembly through a spring. Compared with a common seat, the utility model has the advantages of remarkably weight reduction, low manufacture cost, and convenient use and maintenance, and greatly increases space for a passenger to get on or off the bus by overturning the seat cushion.
Description
Technical field:
The utility model relates to a kind of Chain cushion turning device.
Background technology:
Along with country controls the increasing of the dynamics of super, limit for tonnage, in the epoch of weight metering charging, the lighter heavy-duty truck of conducting oneself with dignity is more popular with users.In this case, the seat lightweight is good means.
The cushion turning device of domestic automobile seat is applied to the chair for tourist conductor of long-distance bus more at present---by the upset of four-bar linkage realization cushion, structure is comparatively complicated, cost is higher, needs are lubricated.
Summary of the invention
The purpose of this utility model provides a kind of light-duty cushion turning device.
The technical scheme that the utility model is taked is:
A kind of light-duty cushion turning device, comprise seat frame welding assembly, seat frame welding assembly flexibly connects with seat back-rest framework welding assembly and underframe welding assembly successively by heterotypic bolt, underframe welding assembly flexibly connects by stove bolt and positioning plate, and positioning plate links to each other with seat back-rest framework welding assembly by spring.
Described positioning plate one end is provided with stepped retaining head.
Described underframe welding assembly comprises L template and under(-)chassis.
The beneficial effects of the utility model are: this structure applications is compared common seat behind the heavy motor vehicle seat, loss of weight is obvious, and is cheap for manufacturing cost, uses easy to maintenance; After the cushion upset, increased occupant's the space of getting on or off the bus greatly.
Description of drawings
Fig. 1 is a constructional drawing of the present utility model;
Fig. 2 is the utility model fundamental diagram;
Fig. 3 is the utility model positioning plate constructional drawing;
Wherein: 1. seat frame welding assembly, 2. underframe welding assembly, 3. seat back-rest framework welding assembly, 4. spring, 5. positioning plate, 6. heterotypic bolt 7. hexagon nut with flanges, 8. stove bolt, 9. retaining head, 10.L template.
The specific embodiment
A kind of light-duty cushion turning device, comprise seat frame welding assembly 1, seat frame welding assembly 1 flexibly connects with seat back-rest framework welding assembly 3 and underframe welding assembly 2 successively by heterotypic bolt 6, underframe welding assembly 2 flexibly connects by stove bolt 8 and positioning plate 5, and positioning plate 5 links to each other with seat back-rest framework welding assembly 3 by spring 4.
The utility model inversion principle:
A) locking of cushion:
Underframe welding assembly overturns around heterotypic bolt, when stepped position, positioning plate end slides on the underframe welding assembly L bracket edge, and underframe welding assembly locking.(as shown in Figure 2)
B) release of cushion:
After the upset of underframe welding assembly, continue to apply application force, when the L bracket slippage goes out stepped position, positioning plate end on the underframe welding assembly, influenced by spring tension, positioning plate return, the release of underframe welding assembly along reverses direction.
