Seat base plate and seat with same

Abstract

The invention relates to a seat base plate and a seat with the same. The seat base plate comprises a pallet main base, a seat support plate, a movable support part and a pair of movable support plates, wherein the seat support plate is arranged above the pallet main base; the front end of the movable support part is connected with the seat support plate in a pivoting way, the lower end of the movable support part is connected with the pallet main base in a pivoting way, and the rear end of the movable support part is connected with a seat backrest; the front end and the rear end of the movable support part can pivot by taking the lower end as a supporting point; the pair of movable support plates are arranged in front of the movable support part; the upper end and the lower end of each movable support plate are connected with the seat support plate and the pallet main base in a pivoting way, respectively, so that the seat support plate can be supported in a balanced way when moving along with the movable support part; an elastic part for resisting the backward rotation of the movable support part is arranged on a pivot through which the movable support part is connected with the pallet main base. After the seat base plate is adopted, a user can feel a proper sense of pressure when leaning against the backrest, and the friction between the backrest and the back of the user can be reduced.

Description

technical field [0001] The invention relates to a seat chassis and a seat with the seat chassis. Background technique [0002] At present, the design of the support chassis of the seat is more complicated in order to realize the reclining of the seat back. There are many parts and especially many screws must be used, which is prone to damage or loose screws, resulting in failure. At the same time, because the reclining design mostly uses different modes of springs to bear the reclining pressure of the backrest, it is difficult to accurately adapt to the user's weight or activity conditions, and often produces a sense of pressure that is too light or too heavy when reclined, so more components are required For calibration purposes. In addition, the distance between the chair back and the seat seat changes when the chair back is reclined, and the chair back rubs against the user's back, causing discomfort. Contents of the invention [0003] The main purpose of the present ...

[0002] The current design of the support chassis of the seat, in order to realize the backrest of the seat, the design is more complicated, there are many parts and especially many screws must be used, which is prone to damage or loose screws, resulting in failure

At the same time, because the reclining design mostly uses different modes of springs to bear the reclining pressure of the backrest, it is difficult to accurately adapt to the user's weight or activity conditions, and often produces a sense of pressure that is too light or too heavy when reclined, so more components are required For tuning purposes

In addition, the distance between the back of the chair and the seat changes when the back of the chair is reclined, causing friction between the back of the chair and the back of the user, causing discomfort
