Description

A dual powered seat

technical field

The invention relates to a mechanical device, in particular to a seat.

Background technique

Currently common, generally there is a reclining seat, which allows the user to extend the footboard forward and recline the backrest relative to the seat. These existing seats typically offer three basic positions: a standard, non-reclining, closed position for a sitting position; an extended position for a reclining position; and a reclined position for a sleeping position. In the closed position, the seat is in a generally horizontal orientation and the backrest is configured generally upright. Additionally, if the seating unit includes a footboard to which the mechanism is attached, the mechanism is folded such that the footboard does not protrude. In the extended position, the footboard is extended in front of the seat while the backrest is still sufficiently upright to allow the user of the seat to comfortably watch television or the like. In the reclined position, the backrest pivots rearward from the extended position into an obtuse relationship with the seat for lounging or sleeping. This kind of reclining seat generally adopts a motor drive device. In order to realize the above-mentioned several functions, many connecting rods are arranged on the seat bracket, which increases the number of accessories, increases the cost, and makes the adjustment unreliable. The structure becomes more complex.

For example, the Chinese patent with the publication number CN204444914U discloses a remote-controlled adjustable office chair for anti-overturning, including a connecting rod, a chair back support arm, a chair back, a seat cushion, a horizontal support rod, a No. 1 pull rod, a No. 2 pull rod, and a controller. , No. 1 crank rod, No. 2 crank rod, No. 3 crank rod, electric cylinder, base, chute, heater, front bracket and rear bracket, it is characterized in that the bottom of the base is provided with an anti-skid pad, and the base The upper left side of the base is vertically provided with a front bracket, and the middle part of the front bracket is provided with a No. The tops of the front bracket and the rear bracket are horizontally hinged with a horizontal support rod, the middle position of the horizontal support rod is vertically hinged with a No. 1 crank rod, and the bottom ends of the No. 1 crank rod are respectively hinged with a No. 2 crank. Rod and No. 3 crank rod. The lower end of the No. 3 crank rod is hinged with the slider. cylinder, the left end of the No. 2 crank rod is hinged to the bottom of the left end of the seat cushion, the left end of the No. 2 crank rod is provided with an adjusting bolt on the No. 3 back-shaped groove, and the No. , the top of the No. 2 pull rod is hinged to the bottom of the seat cushion, the middle part of the No. 1 crank rod is hinged with a No. 1 pull rod, the right end of the No. 1 pull rod is hinged to the upper side of the middle part of the seat cushion, and the top of the seat cushion is fixed on The left side of the top of the chair back, the chair back is fixed on the top of the chair back support arm, the bottom end of the chair back support arm is hinged on the rear bracket, the chair back support arm is provided with a No. 1 back-shaped groove, the The No. 1 return-shaped slot and the No. 2 return-shaped slot are connected by a connecting rod, and both ends of the connecting rod are provided with adjusting bolts, and a heater is provided on the upper side of the chute, and the electric cylinder and the heater are All are connected with the controller through the control line. In the present invention, when the adjustment function needs to be realized, it is necessary to manually adjust the adjusting bolts at both ends of the connecting rod, which is very inconvenient, and there are as many as 6 connecting rods including the crank rod in the present invention, and the connecting rods in the chute Sliding drives the adjustment of the whole seat support, and the sliding direction of the slide bar in the chute is not easy to control, so the invention cannot be implemented.

The Chinese patent with the publication number CN103622360A discloses a multifunctional sofa, including a sofa main body and a sofa support cooperating with the sofa main body. The sofa main body includes a seat cushion, footrests, backrest and armrests. The connecting rod assembly below and hinged to it, the pedal bracket hinged to the seat cushion support and the connecting rod assembly respectively and can be folded telescopically, the arc support plate hinged to the bottom of the link assembly and used to support the seat cushion support, slidingly arranged on the arc support The slide bar on the board and the backrest bracket arranged at the rear end of the cushion bracket; wherein, the back of the backrest is arc-shaped and connected with the backrest bracket, one side of the backrest bracket is hinged with the slide bar, and the other side is hinged with the cushion bracket. Only one driving device is provided in the present invention, and the driving device drives the connecting rod assembly and the backrest bracket to respectively make the pedal bracket stretch and fold, and the backrest bracket slide and tilt, thereby realizing the adjustment of the sitting, lying and sleeping postures of the sofa to adapt to the body shape of the user. Changes, the connecting rod assembly includes five connecting rods, more accessories, increased manufacturing costs, poor coordination, and the structure becomes more complicated to achieve the same function.
