[detailed description of the invention]
The structure of the horizontal back cushion of the utility model embodiment as shown in Figures 1 to 12, comprises back cushion 1, cushion 2 and adjustable for height support.
Adjustable for height support comprises the inner frame 3 of U font, outside framework 4 and two expansion links 100 of U font.Inner frame 3 is fixed on the bottom surface of back cushion 1, and the lower end of the rear end of outside framework 4 and inner frame 3 is hinged.On outside framework 4, cover has foot pad 401.
Expansion link 100 comprises upper boom 5 and the lower beam 6 of mutual fit, and the rear portion of the upper end of upper boom 5 and inner frame 3 is hinged, and the middle part of the lower end of lower beam 6 and outside framework 4 is hinged.
Back cushion 1 comprises the fixed head of airfoam cushion 101 and inner frame, and there is a chest hole 103 front portion of airfoam cushion 101.
The fixed head of inner frame is divided into 102, three stripe board 102 of three bar shaped planks to be arranged along top frame 301 and two frames 302 of inner frame 3 respectively, and three stripe board 102 are embedded in airfoam cushion 101 inside.In stripe board 102, be embedded with one or two four paws nut 104, have 6 screw holes 303 on inner frame 3, inner frame hold-down screw 106 screws in the screwed hole of four paws nut 104 through the screw hole 303 on inner frame 3, inner frame 3 is fixed on to the bottom surface of airfoam cushion 101.
There is the groove 105 that holds inner frame 3 and outside framework 4 bottom surface of airfoam cushion 101, and when support folds, horizontal back cushion 1 inner frame 3 and outside framework 4 are embedded in groove 105.
Cushion 2 is connected and fixed by connecting band VELCRO 7 with back cushion 1 and support.In the time that back cushion 1 erects highlyer, user is sitting on cushion 2, leans against on back cushion 1, has cushion 2 to draw, and back cushion 1 can not move forward; If do not have cushion 2 to draw, user leans against on back cushion 1, and back cushion 1 will inevitably move and by not firm.
Keep flat when back cushion 1 approaches, in user lies prone on back cushion 1, cushion 2 is used for pad below user's knee, avoids user's the direct kiss the earth of knee, and comfortableness is good.
The anterior chest hole 103 of airfoam cushion 101, can reduce back cushion 1 compressing to chest and cardia on all fours time, and comfortableness is good.
It is CN201320565015.3 that the expansion link 100 of the utility model embodiment adopts the patent No., name is called the Telescopic rod structure described in " a kind of toe board " utility model patent, as shown in Fig. 9 to Figure 12, expansion link 100 comprises lock dog 11, slide block 10 and stage clip 12, the body of rod of upper boom 5 is hollow rod body, and the body of rod of lower beam 6 is inserted in the hole of upper boom 5 hollow rod bodies.Upper boom 5 bodies of rod comprise the slotted eye axial arranged along upper boom 5, and one side of slotted eye is for rising as high as the banks, and another side is serrated slot.Serrated slot is positioned at the stage casing of rising as high as the banks, and sawtooth upwards.Slide block 10 comprises pilot hole, and the bottom of lower beam 6 bodies of rod comprises lock dog 11 holes, and lock dog 11 is arranged in lock dog 11 holes, the upper end of lock dog 11 and lower beam 6 bodies of rod are hinged, the lower end of lock dog 11 comprises the locking shaft crossing out, and locking shaft, through the pilot hole of slide block 10, is inserted the slotted eye of upper boom 5 bodies of rod.Stage clip 12 is arranged in lock dog 11 holes, between lower beam 6 bodies of rod and lock dog 11, pushes locking shaft to serrated slot.The pilot hole of slide block 10 is wide at the top and narrow at the bottom L shaped, and the width on top is corresponding to the width of slotted eye, the width of bottom and position with rise as high as the banks correspondingly, slide block 10 is slidably matched with the endoporus of upper boom 5 bodies of rod.
If the patent No. is as described in CN201320565015.3 utility model description and accompanying drawing, when this expansion link stretches, can be stretched to the length needing, and backhaul self-locking; Need to adjust to shorter length time, as long as move maximum length to, compression after releasing self-locking.
So, when the horizontal back cushion of the utility model embodiment need to strengthen support angle, can directly pull backward back cushion 1, allow expansion link be elongated to suitable position self-locking, while reducing support angle as needs, pull backward back cushion 1 to angle maximum position, remove after expansion link self-locking, backup pad 1 was to keeping flat position in the past, i.e. support minimum angles position; And then adjust as required angle, use easily.
Expansion link of the present utility model can also adopt the expansion link of introducing for 200910056237.0,201220689410.8,201220364667.6 patents such as the patent No., but compared with the expansion link that these expansion links are CN201320565015.3 introduction with the patent No., adjustment is got up and is slightly bothered a bit.
