Abstract
The utility model relates to a structure improvement of a backrest cushion, which is mainly characterized by being formed by coating a buffering layer on a back plate to cover an outer sleeve, wherein the back plate is formed by using two sides of a main plate to connect movable side plates, so that the backrest cushion can be bent along the radian of a chair back so as to support the back part and two sides of a user.
Description
Technical field
The utility model is a kind of structural improvement of back cushion, mainly be on backboard, to cover cushion and coating outer cover constitutes, and this backboard is to form with the both sides connection activity side plate of mainboard, impels the backboard both sides to have in response to the movable design of chair back shape to lie for the user to lean on.
Background technology
Back cushion is the supporting construction between a kind of user of the being seated in back and the chair back, to remedy the difference between chair tool ergonomic designs and the user's build, allow different users can keep good sitting position and comfortableness easilier, so the product of back cushion occupies great demand on market always.
And in the structural design of known back cushion, main all is to cover cushion and (or setting up the back pad that can adjust curvature again) that coating outer cover constituted on a backboard, therefore when the user is seated in the chair back with back cushion, back cushion has just replaced the ergonomic designs of this position of the chair back fully, and because can not fit (the different of its size and arc curvature are respectively arranged) between the back of back cushion and chair back front fully, so often between the back of back cushion and chair back front, produce great space (as shown in Figure 1), promptly cause being provided with of back cushion can take great seat support area, reduce the user in a large number and can be sitting in area on the seat support, not only influence comfortableness, and the existing ergonomics arc curvature design of the chair back also can be lost because of the setting of back cushion (when for example chair back both sides have the design that coats both sides, user back forward originally, also can be ineffective because of inserting of back cushion), the problem that causes back cushion and chair back function to cancel out each other.
The utility model applicant is in view of above-mentioned disappearance, the structural design of the known back cushion of dark feel has its weak point, therefore then is engaged in the experience of Specialty Design, manufacturing for many years with it, actively research and development improvement, under the consideration of each side's condition and cost, the pains utility model goes out the composition of this structure.
The utility model content
The purpose of this utility model is to provide a kind of structural improvement of back cushion, to solve the defective that exists in the known technology.
For achieving the above object, the structural improvement of the back cushion that the utility model provides, mainly be to cover cushion and coating outer cover constitutes on backboard, wherein: backboard is to form with the both sides connection activity side plate of a mainboard, and the movable side plate of back cushion is along the radian of the chair back and bending.
The structural improvement of described back cushion, wherein mainboard and movable side plate are to link via hinge.
The structural improvement of described back cushion, wherein mainboard and movable side plate are that pivot joint constitutes.
The structural improvement of described back cushion, wherein mainboard and movable side plate are distinctly fixing and link via the two ends of pliable and tough material.
The structural improvement of described back cushion wherein is provided with on the mainboard after the adjustable back pad and covers cushion again, drives adjustable back pad in response to different users's build.
The utility model can reach following benefit after implementing:
Because the backboard in the utility model back cushion is the both sides connection activity side plate with a mainboard, so the movable side plate of both sides has the characteristic of relative mainboard pendulum angle, in a single day when therefore being placed on back cushion between the user back and the chair back, can be compressed on the mainboard by lying of the relative back cushion of user by power, and the movable side plate that makes both sides is along the arc curvature of chair back ergonomics and swing forward (for example the both sides of the chair back have towards frontal arc when bent), form to hold up with the both sides that are coated on the user back and embrace, allow the user use back cushion to reach under the purpose of enduring waist, can also obtain simultaneously the ergonomic designs of the chair back, and because back cushion of the present utility model can't take too many seat support area (can not produce big space between the back cushion and the chair back), so the area that the user can be sitting on the seat support is very sufficient, can keep best comfortableness.

The specific embodiment
Be the function and benefit that can understand really that structure of the present utility model is formed and can be reached, following conjunction with figs. and embodiment do to be situated between in detail explanation.
The structural improvement of back cushion of the present utility model, mainly be on backboard 1, to cover cushion 2 and coating outer cover 3 is constituted (as Fig. 2, shown in Figure 3), its dorsulum 1 be form with the both sides connection activity side plate 12 of a mainboard 11 (with movable side plate 12 relatively mainboard 11 fixed form of swinging be principle, can adopt hinge joint, articulate in conjunction with or distinctly be fixed on mainboard 11 with the two ends of pliable and tough material, movable side plate 12 can, because the known mode that can adopt is extremely many, so repeat no more), make the back cushion 10 can be along the radian of the chair back 20 and bending, to support user's back and both sides.
Form technology as can be known by said structure, in the backboard 1 movable side plate 12 be with relative mainboard 11 swing forward be main purpose (as shown in Figure 4, also can constitute the state of forward and backward swing, as shown in Figure 9), and cooperate cushion 2 cover and after overcoat 3 coats, can allow back cushion 10 keep setting power by the setting of cushion 2, so back cushion 10 is still very easily when carrying.And in the process of using, need only back cushion 10 is placed between the user back and the chair back 20 (as Fig. 5, shown in Figure 6), just can depend on power to be pressed in (cushion 2 that is mainboard 11 places can provide the very function of waist) on the mainboard 11 by lying of the relative back cushion 10 of user, and the movable side plate 12 that makes both sides is along the arc curvature of the chair back 20 ergonomics and swing forward (for example the both sides of the chair back 20 have towards frontal arc when bent), the both sides that make activity side plate 12 and cushion 2 be coated on the user back form to hold up and embrace, not only can reach the very purpose of waist after allowing the user use back cushion 10, and can also obtain the ergonomic designs of the chair back 20, moreover, because back cushion 10 of the present utility model can't take too many seat support area (20 of the back cushion 10 and the chair back can not produce big space), so the user can be sitting on the very sufficient seat support area, keep best comfortableness.
Other is the person, among the embodiment again of the utility model back cushion 10, adjustable back pad 4 backs can be set on mainboard 11 and cover cushion 2 (as shown in Figure 7) again, can drive adjustable back pad 4 in response to different users's build, auxiliary user endures waist with the convex arc-shape attitude that changes this place's cushion 2, urgees to make the effect of back cushion 10 more powerful.
Continue again, the scope of application of the utility model back cushion 10 is very extensive, except general seat, office chair, also be well suited for being implemented in (as shown in Figure 9) on the wheelchair 30, allow sufferer use wheelchair 30 lie by the time, easier just sitting and keep comfort (sufferer on the wheelchair 30 belongs to severe usually or action edge is not good owing to need be sitting in, thus more need sufferer lie by the time, allow back cushion 10 form arc along the back and hold up the state of embracing).
