Description
Technical Field
The invention belongs to the technical field of seat design.
Background
The seat back is adjustable, so that the use convenience of the seat can be greatly improved, and the seat back is one of basic functions of the conventional automobile seat. The mode of the back of the chair is all set up a horizontal rotating shaft in the back of the chair bottom to current seat, rotates the back of the chair around this pivot to adjust the back of the chair angle, adjust the drawback of the back of the chair like this and lie in: the angle of the back of the chair is completely independent of the seat cushion, and the position of the seat cushion is fixed no matter the angle of the back of the chair, namely the available seat cushion length of the seat is fixed. When the chair back is in a vertical state, a user needs a shorter cushion length to enable the shank part to be capable of hanging to the front side of the chair, so that the comfort is improved, and when the chair back is inclined to enable the whole chair to form a state similar to a reclining chair, the user needs a longer cushion length to enable the shank part to be supported by the cushion, so that the comfort is improved. The above-mentioned way of adjusting the chair back of the chair is obviously not able to meet the user's needs in different periods of time.
Disclosure of Invention
The invention aims to provide a chair with adjustable chair back angle and adjustable seat cushion position.
The chair with the adjustable chair back angle and the adjustable seat cushion position comprises a base, a seat cushion and a chair back, and is characterized in that the bottom end of the chair back is connected with the base through a first horizontal rotating shaft, so that the angle of the chair back can be adjusted; the seat cushion is movably arranged on the base through a horizontal guide rail and is provided with a driving mechanism for driving the seat cushion to move along the horizontal guide rail, or the seat cushion is provided with a linkage mechanism linked with the chair back; the lower part of the chair back is provided with a hollow part at the position corresponding to the seat cushion.
When the angle of the chair back of the chair is adjusted, the driving mechanism or the linkage mechanism can be utilized to drive the seat cushion to move along the horizontal guide rail, so that the seat cushion and the top end of the chair back move in the back direction in the horizontal direction, and the seat cushion is closer to the chair back when the chair back is in a vertical state, the available length of the seat cushion is shorter, the lower leg part of a user can be enabled to be hung to the front side of the seat cushion, and the comfort is improved; when the chair back inclines to enable the whole chair to form a state similar to a reclining chair, the distance between the seat cushion and the chair back is increased, the seat cushion protrudes forwards, the shank part of a user can be supported by the seat cushion, the user can lie on the chair almost flat, and the comfort is improved. The hollow-out part of the chair back can prevent the chair back from interfering with the seat cushion when the angle of the chair back is adjusted.
Specifically, the linkage mechanism is composed of a first gear arranged on a first horizontal rotating shaft, a second gear arranged on a second horizontal rotating shaft and a rack arranged at the bottom of the seat cushion, the second horizontal rotating shaft is rotatably arranged on the base, the first gear is meshed with the second gear, and the second gear is meshed with the rack. When the first horizontal rotating shaft rotates to adjust the angle of the chair back, the first gear drives the second gear to rotate reversely, the second gear drives the seat cushion to move through the rack, so that the linkage of the seat cushion and the chair back is realized, and a user can only adjust the angle of the chair back, and can simultaneously adjust the seat cushion.
Specifically, the driving mechanism has the following two structures:
1. the driving mechanism is composed of a second gear arranged on a second horizontal rotating shaft and a rack arranged at the bottom of the seat cushion, the second horizontal rotating shaft is rotatably arranged on the base, the second gear is meshed with the rack, and a rotating handle is arranged at the end part of the second horizontal rotating shaft. When the second horizontal rotating shaft is rotated through rotating the handle, the seat cushion can move along the horizontal guide rail through the matching of the second gear and the rack, and the purpose of adjusting the position of the seat cushion is realized.
2. The driving mechanism is composed of a rack arranged at the bottom of the seat cushion, a screw rod meshed with the rack and a motor driving the screw rod to rotate, the screw rod is rotatably arranged on the base, and the motor is fixed on the base. When the motor drives the screw rod to rotate, the seat cushion can move along the horizontal guide rail through the matching of the screw rod and the rack, and the purpose of adjusting the position of the seat cushion is achieved.
When the driving mechanism is adopted to adjust the position of the seat cushion, the angle adjustment of the seat cushion is separated from the angle adjustment of the chair back, and a user can respectively adjust the angle of the chair back and the position of the seat cushion according to the actual condition of the user, so that the comfort is improved.
Furthermore, when the chair back is in a vertical state, the chair back is positioned in the center of the seat cushion, so that when the chair back is vertical, the chair is a bidirectional chair with two surfaces capable of being used for sitting, and when only one person sits on the chair, the angle of the chair back can be adjusted, so that the chair back is a deck chair, and the comfort level of passengers is improved. The chair back can incline to two directions to meet the use requirements of passengers in different directions.
Furthermore, chair back guide rails are arranged on two sides of the hollow portion of the chair back, a plurality of movable rods which are arranged at intervals are movably mounted on the chair back guide rails, and springs are arranged between every two adjacent movable rods of the chair back guide rails. Above-mentioned movable rod can follow the back of the chair guide rail and remove, and when the back of the chair was the vertical state, the movable rod was under the spring action of spring, and the distribution that is nearly even was in fretwork portion department, provides the support for passenger's back, and when the seat was the tilt state, the movable rod was pushed by the seatpad, moves to the top direction of the back of the chair along the back of the chair guide rail, can not prevent the angle modulation of the back of the chair.
Specifically, lantern rings are arranged at two ends of the movable rod, and the chair back guide rail penetrates through the lantern rings, so that the movable rod is movably arranged on the chair back guide rail.
The seat can adjust the angle of the seat back and adjust the position of the seat cushion at the same time to change the available length of the seat cushion, thereby improving the comfort of passengers and being very suitable for automobile seats.
