Description

Bed back support

This utility model relates to Bed back support

The patient who lies up can feel general fatigue after long-time bed, often need to rest in bed bed and go up rest, also needs seat when having a dinner on bed.At this moment often need the nursing staff that quilt etc. is deposited in patient behind, make it become the semireclining posture, it is cumbersome not only to stack quilt, and the time is long slightly, and quilt is behind pressed sunken, and supporting role weakens, and the layback of patient's upper body also needs quilt is stacked again.Existing sick bed can suitably shake head of a bed part, but because of the quilt on the bed is thicker, the angle that the head of a bed is lifted is weakened, is ramped shaped, and patient tends to glide, and cosily seat is on bed.

The purpose of this utility model is to provide a kind of Bed back support, when patient needs seat time-out in bed, this support is placed on patient behind as the usefulness of backrest, and its adjustable angle feels comfortably cool patient's seat and is difficult for gliding on bed.Not the time spent desirable down, fold up, be convenient to deposit.

This utility model Bed back support is achieved in that 1 upright backrest and 1 frame-type base is set, and pony sill places the back of backrest, and backrest bottom and base are hinged and couple together with the corner detent mechanism.

Back bracket on the internal crucible after patient's seat rises, is put in patient behind, and the base rear end of back rest back props up and peaks at head of a bed place, adjusts angle orientation mechanism backrest uprightly or is slightly retreated.Because this back bracket backrest is as the backrest of sofa or soft chair, can feel comfortably cool when patient relies on, and backrest can adjust gradient according to patient's needs, easy to use, can make patient's seat and be difficult for gliding for a long time.When patient need couch, can fold and place with this support by taking off on the bed, operation subtracts list.Used corner detent mechanism is common mechanisms such as furniture, as used among Fig. 1 be connecting rod 4 hinged slide blocks 5, slide block places on the guide rail 6 of base 2; Also can adopt clutch type corner detent mechanism, form is more, further specifies in description of drawings again.

Be described further below in conjunction with accompanying drawing.
