Technical field
The present invention relates to a kind of seat, concretely relate to a kind of there is seat swing function and seat with completely new
The cushion size regulating mechanism and seat of size regulatory function.
Background technique
Chair obtains the universal approval of people and likes, and is existing as widely used seat tool in people's work, life
Act on behalf public, one of essential furniture in domestic environment.Chain cushion in the prior art cannot change cushion size, this
Sample is just unable to satisfy different height, the demand of different building shape user.
A kind of Chinese patent literature (day for announcing: on May 10th, 2017, notification number: CN106627864A) adjustable cushion,
Including left side cushion, right side cushion, and the adjusting that the two can be driven to separate to two sides or close up to centre
Mechanism, and left side cushion, right side cushion form gap backwards in front end in opposite directions, and which can
The buttocks size for adapting to bicyclist realizes and compels to the private parts zero-pressure of bicyclist, brings bicyclist and comfortably experience.
Chinese patent literature (day for announcing: on March 11st, 2015, notification number: CN102551392B) is open save one kind can be with
The cushion length elongation of Chain cushion is set to be most suitable for the seat with cushion having adjustable length of state.The cushion adjustable in length seat
Chair tool moved forward and backward for cushion and using actuator to be displaced the front part of cushion forward and backward come
Change the movable member of cushion length.It is configured with detector in movable member side, which utilizes the front side portion for making cushion
Divide pressure-operated when being displaced and abutting forwards with the lower limb of seated person, and stops actuator.
Although above-mentioned technical proposal is also disclosed the seat for adjusting cushion length, but it is impossible to meet different building shapes
Different demand when demand, sitting posture and standing auxiliary, and the demand of different hobbies.
Summary of the invention
In the presence of overcoming the shortcomings of the above-mentioned prior art, and one kind is provided and can change seat
Size and form is padded, the demand for being able to satisfy different building shape user sitting posture and standing when assisting also is able to satisfy the happiness of different users
It is good, and the cushion size regulating mechanism and seat of comfortable health.
The present invention realizes that technical solution used by its first goal of the invention is:
A kind of cushion size regulating mechanism, comprising:

On engaging lug, when adjusting the bottom of the upward footstock plate the right and left seat board one of executive item and seat board two, the centre of seat board is motionless, seat
The seat board one and seat board two of plate the right and left will with adjust moving up and down for executive item and change angle, when seat board angle to
On when becoming larger the size of seat board just increase, the size of seat board just reduces when angle becomes smaller downwards, realizes seat seat board size
It adjusts, so that seat has more practicability.In order to increase comfort level, the surface of seat board can also coat the tender fabric in Shanghai.
As shown in figure 15, which can adapt to human body sitting posture so that 360 degree of movements are automatic, carry out any
Angle change, 360 degree for realizing seat freely adjust angle.Wabbler mechanism includes swaying base 130, vacillating actuator mechanism
131, swinging driving resetting-mechanism 132 and fixed mechanism 133.
The setting of swaying base 130 is in shield, and swaying base is internally provided with arc swinging bottom surface 135 and waves execution machine
Hemispherical on structure 131 waves the cooperation of cambered surface 134, swaying base 130 be with flexible glue injection molding, swaying base 130 it is another
A effect is a flexible glue bucket for preventing clamp hand.Base body and swaying base 130 also can be set to an entirety.
Hemispherical on vacillating actuator mechanism 131 is waved cambered surface and is matched with the arc swinging bottom surface 135 in swaying base 130
It closes, the internal ring wall inside vacillating actuator mechanism 131 is and the external annulus contract on swinging driving resetting-mechanism 132.Swinging driving is multiple
Position mechanism 132 is flexible glue resilient sleeve, and fixation hole is the axis with base body there are two settings on swinging driving resetting-mechanism 132
On mounting hole cooperation.
Fixed mechanism 133 is a fixed plate, sets that there are two cylindrical screw installing holes on fixed mechanism 133, for that will shake
Oscillatory forces resetting-mechanism 132 is fixed on axis.Accessory is placed to installation from top to bottom in order, it will be on fixed mechanism 133
Cylindricality mounting hole thus will through the fixation hole on swinging driving resetting-mechanism 132 with the mounting hole on screw connection axis
Entire wabbler mechanism is connected as an entirety, and seat board thus completes entire seat on screw connection vacillating actuator mechanism 131
Installation.
Shown in Figure 15: the hemispherical of vacillating actuator mechanism 131, which waves cambered surface 134 and is internally provided with arc with swaying base, shakes
Pendulum bottom surface 135 radian be it is different, hemispherical wave cambered surface 134 cambered surface be less than arc swinging bottom surface 135, swaying base
It is all mounted in vacillating actuator mechanism 131 on the axis of base body, their center of circle is all axis, vacillating actuator mechanism
131 meetings are waved for 360 degree in the radian difference range that hemispherical waves cambered surface 134 and arc swinging bottom surface 135.Flexible glue resilient sleeve
Swinging driving resetting-mechanism 132 is also mounted on axis, and the upper end of swinging driving resetting-mechanism 132 is fixed mechanism 133
It is fixed on the upper end of axis, the outer wall of swinging driving resetting-mechanism 132 and the inner wall of vacillating actuator mechanism 131 are to agree with completely
, when vacillating actuator mechanism 131 is waved with axis, the inner wall of vacillating actuator mechanism 131 can squeeze swinging driving reset
The outer wall of mechanism 132, swinging driving resetting-mechanism 132 are by flexible glue machine-shaping, elasticity as rich as Croesus, when waving execution machine
When structure 131 waves, swinging driving resetting-mechanism 132 will constitute an elastic device, become vacillating actuator mechanism 131 and wave
With the power of reset.
Seat board is installed on wabbler mechanism, and user is sitting on seat board, and as human body sitting posture back and forth or left and right rolls, cushion is just
360 degree of any activities in scope of activities can be changed with human body sitting posture, realize automatic adaptation human body sitting posture any angle variation
Function.
