Nursing Pillow

Abstract

A nursing pillow includes: a first abutting unit, a second abutting unit and a cover unit. The cover unit has a main body and an opening configured on the main body. The main body defines an accommodation chamber accessed via the opening and in which the first abutting unit and the second abutting unit are allowed to be stacked with each other and extended along the first axial direction. The cover unit further has an adjusting assembly disposed to seamlessly encompass an outer side of the main body, wherein the adjusting assembly is operated in a way such that the main body generates two thickness variations along the first axial direction. Thereby, the present invention is able to generate several thicknesses for the nursing pillow.

         6 . The nursing pillow according to  claim 5 , wherein a first length extending along the third axial direction is defined between the inner region and each of the connecting regions, and a second length extending along the third axial direction is defined between the outer region and each of the connecting regions, the first length is not smaller than one third of the second length. 
     
     
         7 . The nursing pillow according to  claim 1 , wherein the nursing pillow further comprises a back cushion unit having a rest cushion adapted for a user's back to lean against and a belt connecting to the rest cushion; the first abutting unit, the second abutting unit or the cover unit is detachably connected with the belt. 
     
     
         8 . The nursing pillow according to  claim 7 , wherein the rest cushion of the back cushion unit has a cushion core, a covering member covering an outer side of the cushion core, an assembly configured on the covering member for the belt to pass through, and a securing member disposed on the covering member adjacent to the assembly, where the securing member is operated to open and close the assembly; the cushion core and the covering member together define a space which is accessed with the assembly; the belt has two connecting end parts at its two ends and a middle part connecting between the connecting end parts, the middle part is disposed in the room such that the connecting end parts expose from two ends of the covering member via the assembly. 
     
     
         9 . The nursing pillow according to  claim 1 , wherein the nursing pillow further comprises a back cushion unit having a rest cushion adapted for a user's back to lean against and a belt connecting to the rest cushion, two ends of the belt are connecting to the cover unit; the rest cushion has a cushion core, a covering member covering an outer side of the cushion core, and at least one positioning member connecting to an outer side of the covering member; the positioning member is connecting to the covering member by two ends and cooperating with the covering member to define a positioning aperture for the belt to pass through.
