AI Technical Summary
The shaped cotton of traditional seat cushions is insufficient, which leads to hard sitting for people with heavy weight and soft sitting for people with light weight, and poor comfort. The shaped cotton does not rebound well after being pressed, resulting in collapse of the seat cushion and wrinkle of the seat cloth.
It uses memory foam made of polyurethane polymer material, combined with a protective inner panel and seat cloth to form an open unit structure, which has the characteristics of softness, impact energy absorption and quick rebound.
It achieves even distribution of pressure, provides excellent coverage and comfort, prevents the seat fabric from wrinkling, maintains the beautiful appearance of the seat cushion, and helps correct bad sitting posture.

Abstract
Description
[Technical field]
[0001] The utility model relates to a memory foam seat cushion. [Background Technology]
[0002] There are two types of traditional seat cushions: one is a single layer of shaped cotton added to a wooden board; the other is a single layer of shaped cotton added to a seat shell. Among them, the defects of setting a single layer of shaped cotton include: first, when the single layer of shaped cotton is soft, heavy people tend to sit on the bottom and feel like sitting on a hard board, while when the single layer of shaped cotton is hard, light people feel very hard and have poor comfort; second, the single layer of shaped cotton has poor rebound after being compressed, so after sitting for a period of time, the shaped cotton is prone to shrinkage and deformation to a certain extent, and the shaped sponge is prone to collapse, resulting in wrinkles on the seat cloth and poor appearance. [Contents of the utility model]
[0003] The utility model overcomes the shortcomings of the prior art and provides a memory foam seat cushion.
[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0005] A memory foam seat cushion, characterized in that it comprises a bottom shell, a protective inner plate is arranged on the top surface of the bottom shell, a memory foam is sleeved on the top of the protective inner plate, a seat cloth is arranged on the outer cover of the memory foam, and the memory foam is made of a polymer material of polyurethane macromolecule.
[0006] The memory foam seat cushion as described above is characterized in that an inner plate supporting protrusion extending upward is provided at the middle position of the top surface of the protective inner plate, and a foam supporting groove matching with the inner plate supporting protrusion is provided on the bottom surface of the memory foam.
[0007] The memory foam seat cushion as described above is characterized in that: an inner plate annular positioning convex edge extending upward is provided on the top edge of the protective inner plate, and a foam annular positioning groove cooperating with the inner plate annular positioning convex edge is provided on the bottom surface of the memory foam.
[0008] The memory foam seat cushion as described above is characterized in that the supporting protrusion portion is an arc-shaped protrusion portion.
[0009] The memory foam seat cushion as described above is characterized in that: a bottom shell cavity is provided on the top surface of the bottom shell, a protective inner plate covers the bottom shell cavity to seal the bottom shell cavity, and a transversely arranged reinforcing plate is provided in the bottom shell cavity.
[0010] The memory foam seat cushion as described above is characterized in that a reinforcing plate positioning groove is provided in the concave cavity of the bottom shell, and the reinforcing plate is arranged in the reinforcing plate positioning groove.
[0011] The memory foam seat cushion as described above is characterized in that armrest mounting holes are provided inside the bottom shell.
[0012] The memory foam seat cushion as described above is characterized in that the armrest mounting hole is arranged on the bottom shell at a position below the reinforcing plate.
[0013] The memory foam seat cushion as described above is characterized in that a seat cushion wire control device is provided on the bottom surface of the bottom shell.
[0014] The memory foam seat cushion as described above is characterized in that a bottom shell mounting groove is provided on the bottom surface of the bottom shell.
[0015] The beneficial effects of the utility model are:
[0016] 1. The utility model is provided with an integrated foam memory foam structure, a polyurethane polymer with an open cell structure, which has very soft material properties and strong impact energy absorption capacity. When the molecules of this material are compressed by external force, they will "flow" and shift to fit the contact surface contour of the pressure object, thereby evenly dispersing the pressure to the entire contact surface, providing an excellent wrapping feeling and making you feel less tired even when sitting for a long time.
[0017] 2. The memory foam of the utility model has high elasticity, fast rebound, soft sitting feeling, and a full appearance when matched with the seat cloth. The seat cloth will not wrinkle due to long-term sitting, and the appearance is more beautiful, which can maintain the beauty of the seat cushion for a long time. The memory foam has the characteristics of super softness and super strong wrapping feeling, so that the weight of the user's body can be evenly distributed on the buttocks and thighs, avoiding local pressure, preventing compression of internal organs, avoiding coccyx pain, and helping to correct bad sitting posture.
[0018] 3. The utility model arranges a reinforcing plate on the bottom shell to strengthen the bottom shell and replace the seat wood board, thereby saving wood and making the seat cushion more environmentally friendly.
[0019] 4. The utility model sets a protective inner plate between the bottom shell and the memory foam, which protects the memory foam from damage and destruction when the memory foam is pressed by external force, thereby increasing the cushioning.
[0020] 5. A seat cushion wire control device is provided at the bottom of the bottom shell of the utility model, which can control the lifting, sliding, and tilting and locking of the seat cushion. [Drawings]
