Invention content
The present invention relates to a kind of self-adjusting back-rest means for chair, protects lumbar region and alleviate the pressure of buttocks.
Backrest is self-adjusting, it means that it need not control or order.
The device supplement seat surface being previously mentioned so that the seat surface previously existed, and the purpose of the present invention covers
Be that it increases backrest or improve existing backrest.
The self-adjusting backrest module includes the movable plate of user's setting on it, wherein the plate revolves on the horizontal axis
Turn, which passes through first group of wheel hub for being connected to plate, and the axis is associated with second group of wheel hub of support element is connected to, the branch
Support member can be the chair of self-adjusting backrest to be used or the backrest of easy chair itself, and in this case, it will be referred to as
Pre-existing backrest or it can be the part to form the device fixation backrest, in this case, it will be claimed
For the backrest of device.
At least one set of wheel hub it is adjustable for height, therefore, the height change of first group of wheel hub will change plate rotate on it
Corresponding point, change bar, and the height change of second group of wheel hub by change plate where position at height.
Any element that wheel hub is referred to herein as used as support shaft to allow it to rotate.
The backrest of device should be supported on surface (except other things) thereon based on it and can be of different sizes.
In no user's applied force or with his or her will applied force, which has initial position, and
And it can be run come limiting balance by maximum position and minimum position.
Ideal initial position or resting position are preferably close to vertical line, but this can be leaned on according to pre-existing
The angle of the back of the body or the backrest of device are stopped support element on it and are changed.
The resting position is obtained due to the effect of torsional spring, in the resting position of torsional spring, plate is in big
Vertical position is caused, wherein the torsional spring can be buffered so that user feels comfortable.
When not in use, plate is forced into resting position by torsional spring, which can overcome the gravity of plate simultaneously
It brings it to initial position and maintains it in the position, but allow to surrender under the pressure that it applies when user sits down, no
User can be made to feel to pop up power.
Optionally, the operation of plate can have limitation.
Preferably, the component of movable plate, first and second groups of wheel hubs, axis and support element is included in semi-rigid outer shell,
So that user not can be appreciated that these mechanical organs and reduce by the risk of pinching.
According to above-mentioned, the lower part of plate may include elastic element, the space between the elastic element closed plate and seat surface,
Reduce the risk for clamping pluggable object therein or user's body part.Seat surface is usually connected to by the elastic element
Plate, and can be made of rubber fabric, which may also help in plate and returns to upright position, from there through single member
Two benefits may be implemented in part.
Component including plate, first and second groups of wheel hubs, axis and support element is suitble to related to chair, easy chair or sofa etc.
Connection, wherein may include more complicated automotive seat.
Once being mounted with self-adjusting back-rest means for chair, user will be sitting in approximate horizontal and pre-existing seat surface
On, and by back support on self-adjusting back-rest means for chair.
Preferably, the height of axis is adjustable and will be arranged in above the seat surface of user 12 to 33 centimetres
Between, and preferably between 18 to 27 centimetres.
Pre-existing on chair or easy chair is not supported on by back for its position in self-adjusting backrest
In the case of, self-adjusting backrest can include various subsidiary components to be kept fixed and prevent it from being moved under the weight of user.
Thus, for example, in a possible embodiment, which can include suitable stake, to dig into soft ground,
The soft ground is, for example, mud or sand.
Another possible embodiment can include anti-tracing leg, to secure it to smooth surface.
In the third embodiment, which can include fin, using the fin, user with he or she from body
Weight securing supports, when such as user wants to lie on a bed reading and this will be useful when leaning on the apparatus.
Seat unit can be with handrail or any other element without changing property of the invention.Moreover, plate can have
Curvature, buffer unit is flexible, and rigidity or any other measure are to increase the comfort level of user.
Finally, material can be timber, glued board, plastics, metal, fabric, wicker or any other materials.
The plate can be separated with axis, in order to cleaning, repairing or adjusting etc. for task.

Specific implementation mode
One embodiment of the present of invention is briefly described in a manner of illustrating and not limit its scope below.
The self-adjusting backrest for being added seat surface includes：
Movable plate (1), with sufficient size the back of user is covered intrascapular region from coccyx.
Trunnion axis (3), above-mentioned movable plate rotate on it, the axis by be connected to movable plate first group of wheel hub (2) and
It is connected to second group of wheel hub (4) support of the backrest (6) of described device.
Torsional spring, when it is in resting position, i.e., when not having external force to act on it, which protects plate
It holds in general vertical location.
The device rests on seat surface (10), such as bed or floor.
First group of wheel hub (2) of height-adjustable is connected to movable plate.When first group of wheel hub of change is relative to the opposite of plate
Height and when therefore changing relative altitude of the axis relative to plate, the point that plate rotates on it is changed, and is changed and is applied by plate
Torque.
Axis (3) is further coupled to second group of wheel hub (4) association of the backrest (6) of device.
In this embodiment, second group of wheel hub or height-adjustable, and by changing its height, the height of plate and axis
Degree is changed relative to seat surface.
For the axle position of plate rotate on it at 23 centimetres of height, the normal level away from seat surface is at 12 to 33 centimetres
Between, and preferably between 18 to 27 centimetres.
The action of first group of wheel hub and second group of wheel hub and the trunnion axis being associated allows movable plate in device
Rotated by back so that user is applied to that the power on the top of movable plate is bigger, bigger to the effect of lumbar region, subtracts
The pressure that light buttocks is lifted.
In the embodiment of explanation, self-adjusting back-rest means for chair applies due to the use of person when leaning on it in order to prevent
