Problems solved by technology
[0004] In view of the above-mentioned defects, the object of the present invention is to provide a seat cushion to solve the problem that the seat cushion in the existing large-scale vehicles is relatively heavy, resulting in increased energy consumption, which is not conducive to environmental protection
[0005] Another object of the present invention is to provide a back cushion to solve the disadvantages of the existing large vehicle seat back cushions, which are heavy and lead to increased energy consumption, which is not conducive to environmental protection
[0006] Another object of the present invention is to provide a method for manufacturing seat cushions and back cushions, so as to solve the disadvantages of existing large-scale vehicles that the seat weight is relatively large, resulting in increased energy consumption, which is not conducive to environmental protection

Embodiment Construction
[0029] The present invention will be described in detail below with reference to the accompanying drawings.
[0030] See figure 1 and figure 2 , which are respectively a schematic structural diagram of a seat cushion and a back cushion according to an embodiment of the present invention. The seat cushion 100 and the back cushion 200 are both double-layered structures, the inner layer is a melamine sponge inner core 101, and the outer layer is a polyurethane plastic 102, and the polyurethane plastic 102 tightly wraps the melamine sponge inner core 101 inside.
[0031] The density of the selected melamine sponge inner core 101 in the present invention is only 6KG / M3~8KG / M3, which is far smaller than various materials of cushions and back cushions in existing seats, such as pure polyurethane materials, so it is used as a large-scale transportation tool The material of the seat can reduce the weight of the seat by about 3 / 4, which can effectively save energy consumption and pro...

Abstract
The invention relates to a method for manufacturing a seat cushion and a back cushion of a seat in a large-sized vehicle. The method is as follows: the proportion of polyurethane plastics and melamine sponge is selected according to requirements, and the melamine sponge is made into inner cores of the seat cushion and the back cushion; the melamine sponge inner cores are processed by low-pressure plasma spraying to make the melamine sponge inner cores waterproof and oil resistant so as to satisfy a floatability test; then the polyurethane plastics are coated outside the melamine sponge inner cores; and finally, fire-retardant cloth, padding cloth and decorative cloth are sleeved on the back cushion and the seat cushion in turn. The seat cushion and the back cushion manufactured by the method not only have good vibration performance and sound-absorbing performance, but also have far lighter weight than the seat cushion and the back cushion of the seat in the prior large-sized vehicle, thus the energy consumption of large-sized vehicles can be effectively reduced to protect the environment.
Description
technical field [0001] The invention relates to a seat cushion, a back cushion and a manufacturing method thereof, in particular to a seat cushion and a back cushion for a seat in a large-scale transportation vehicle, and a method for manufacturing the same. Background technique [0002] At present, all kinds of large-scale transportation vehicles are flooded around us, such as planes, trains, passenger cars, etc. The quality of their internal seats will directly affect the passengers. For example, the seats in today's vehicles are not only required to be beautiful and comfortable, but also required to have good vibration characteristics and sound absorption characteristics. More importantly, due to the current increasingly tense energy situation and the increasingly harsh environment, vehicles are required to save energy as much as possible, and the reduction of seat weight can reduce the energy consumption of vehicles to a certain extent. However, the back cushion and the...
