Adjustable cushion for seat

The utility model relates to a cushion structure, in particular to an adjustable cushion which can be arranged on a seat, which can provide a comfortable supporting effect of the waist and the back.

Cushions known to support the body are typically used separately to support different parts of the body, such as a lumbar pad for supporting the waist, a back cushion for supporting the back, which are typically used when in use. Will be placed on the seat and leaning against the back of the chair to provide the support needed for the waist or back, but these traditional cushions are usually of a fixed size and shape and do not have the elastic cushioning function, so for a long time When used, it is easy to cause back pain and other phenomena.

Therefore, some domestic manufacturers have developed a "back-to-back device" such as the domestic bulletin No. M352941, which is used to: when the occupant swings back, it can use the two springs to synchronize activities and generate cushioning effects to get the best ride. comfortability.

However, the above-mentioned backrest device still finds that there is a problem after the actual use: the abutment of the backrest device cannot adjust the position up and down, and therefore, it is not necessarily suitable for each person's body, so it is difficult to provide satisfactory and comfortable support. effect.

In view of this, how to solve the above problems, develop an adjustable cushion for the seat that can adjust the upper, lower, left and right positions to enhance the fit, comfort and support. The idea and research topic of the new creator.

The following is a detailed description of the embodiment shown in the drawings. As shown in the first to fourth figures, the figure discloses an adjustable cushion for a seat, which comprises: a support plate (1), a a set of connecting members (2), a set of elastic supporting members (3), and a set of left and right symmetric cushions (4); the surface of the supporting plate (1) has at least two sets of up and down, left and right symmetry, and is horizontally disposed a long hole (11); the upper and lower ends of the connecting member (2) are detachably connected to the long hole (11), and can be left and right at the long hole (11) a sliding displacement, and a surface of the connecting member (2) is provided with a longitudinal sliding rail (21); a rear end of the elastic supporting member (3) is detachably connected to the sliding rail (21), and is capable of The sliding rail (21) is slidably displaced upward and downward, and the front end is detachably connected to the rear end of the cushion (4); the rear end of the cushion (4) protrudes outwardly from the elastic support member ( 3) Connected positioning block (41).

Wherein, by using the long hole (11), the connecting member (2) and the elastic supporting member (3), the cushion (4) can adjust the positions of the upper, the lower, the left and the right, so as to be different. It can be used by the user of the body type, and can also be used as a back cushion or a lumbar cushion according to the needs of the user, and has the characteristics of being convenient to use, and the manner of use thereof will be described in detail later in FIG.

In the above, a surrounding wall (12) protrudes outwardly from the elongated hole (11), and a proper spacing between the surrounding wall (12) and the elongated hole (11) is formed to form a groove. (13), wherein the upper and lower ends of the connecting member (2) are further provided with a positioning hole (22), and the connecting member (2) is penetrated through the elongated hole by a first screw (10) ( 11) and after the positioning hole (22), the first screw (10) is locked in the groove (13) by the first nut (20); thus, the first Screw (10) It is hidden in the groove (13), so that the rear end surface of the support plate (1) can completely fit on the seat back of the seat, and there is no problem that the sliding is not tight and the arbitrarily sliding occurs.

The third and fourth figures disclose that the elastic supporting member (3) further includes: two first positioning pieces (31), two springs (32), and a second positioning piece (33), the first positioning The front end of the piece (31) is respectively connected to the rear end of the positioning block (41), and the rear end respectively protrudes with two first clamping blocks (311), and the front ends of the two springs (32) are respectively respectively blocked by the first clamping block. (311) fastening and fixing, the rear end of the second positioning piece (33) is connected to the front end of the connecting piece (2), and the two sides of the front end respectively protrude with two second clamping blocks (331). The second latching block (331) respectively fastens and fixes the rear ends of the two springs (32), and the surface of the first positioning piece (31) is further provided with a through hole (34), the first positioning piece (31) respectively, after the second screw (30) is inserted through the through hole (34), and then locked to the positioning block (41), and the surface of the second positioning piece (33) is further provided with a through hole. a hole (35), the second positioning piece (33) is inserted through the sliding rail (21) and the through hole (35) by using a third screw (40), and then the second nut (50) is used to The three screws (40) are locked in the sliding rail (21) of the connecting member (2); The left and right sides of the cushion (4) are symmetrically locked to the two first positioning pieces (31), and the springs (32) are respectively mounted on the rear ends of the two first positioning pieces (31). The rear end of the spring (32) is mounted on the second positioning piece (33), so that when the user's back abuts against the cushion (4), since the spring (32) has an arbitrary deflection The characteristics of the activity, so that when the user's back is moved up, down, left, and right, the cushion (4) will swing with the spring (32) at the same angle to increase the comfort of the user when riding.

In the above, the rear end of the second positioning piece (33) further protrudes with two protrusions (332) embedded in the sliding rail (21); thus, when the user back is on the cushion (4), the left side When the right is active, the second positioning piece (33) can be prevented from rotating by the left and right by the protrusion (332) to strengthen the second The stability of the positioning piece (33) avoids the problem of structural detachment when the external force is violently shaken.

As shown in Figures 5-8, in order to adapt to different body types, the present invention can adjust the position of the two cushions (4) up, down, or left and right, as follows: Figures 5 and 6 reveal To adjust the upper and lower positions of the cushion (4), first loosen the second nut (50) on the second positioning piece (33), and then adjust the second positioning piece (33). In the upper and lower positions, after adjusting the upper and lower positions, the second nut (50) is tightened to complete the adjustment of the upper and lower positions of the cushion (4).

Figures 7 and 8 reveal that if the left and right positions of the cushion (4) are to be adjusted, the first nut (20) at the upper and lower ends of the connecting member (2) is first loosened, and then the adjustment is made. The left and right positions of the connecting member (2), after adjusting the left and right positions, and then tightening the first nut (20), the adjustment of the left and right positions of the cushion (4) is completed.

The structure, features and effects of the present invention are described in detail above with reference to the embodiments shown in the drawings. However, the above description is only a preferred embodiment of the present invention, and therefore the scope of the present invention is not limited by the drawings. Modification changes that are intended to conform to each other should fall within the scope of this new patent as long as they are equal.
