Chair having a detachable backrest panel with a massager

Abstract

A chair having a detachable backrest panel with a massager. The chair includes: a backrest support coupled to one side of back of the chair seat, extending in an upward direction; a first support member coupled to the backrest support in a rotatable manner; a second support member coupled to the backrest support in a rotatable manner; a first backrest rotational axis that is arranged in parallel to the backrest support and has a lower end being coupled to the backrest support and extended therefrom; a second backrest rotational axis that is arranged in symmetry with the first backrest rotational axis with respect to the backrest support and has a lower end being coupled to the backrest support and extended therefrom; a first backrest coupled to the first backrest rotational axis in a rotatable manner; and a second backrest coupled to the second backrest rotational axis in a rotatable manner.

1 . A chair having a detachable backrest panel with a massager, comprising:
 a backrest support coupled to one side of back of the chair seat and extending in an upward direction;   a first support member coupled to the backrest support in a rotatable manner;   a second support member coupled to the backrest support in a rotatable manner;   a first backrest rotational axis that is arranged in parallel to the backrest support and has a lower end being coupled to the backrest support and extended therefrom;   a second backrest rotational axis that is arranged in symmetry with the first backrest rotational axis with respect to the backrest support and has a lower end being coupled to the backrest support and extended therefrom;   a first backrest coupled to the first backrest rotational axis in a rotatable manner; and   a second backrest coupled to the second backrest rotational axis in a rotatable manner,   wherein the first backrest rotates while the first support member engages with the outer peripheral surface on one side of the first backrest, and the second backrest rotates while the second support member engages with the outer peripheral surface on one side of the second backrest.   
     
     
         2 . The chair of  claim 1 , wherein first protrusions which are formed on the outer peripheral surface on one side of the first support member and the first backrest support engage with each other, and wherein second protrusions which are formed on the outer peripheral surface on one side of the second support member and the second backrest support engage with each other. 
     
     
         3 . The chair of  claim 1 , wherein acupressure therapy or massage is performed by the first protrusions engaging with each other and the second protrusions engaging with each other. 
     
     
         4 . The chair of  claim 1 , wherein the first protrusions engaging with each other, and the second protrusions engaging with each other are made from a crystal which contains Jade, rock phosphate, red clay plastic body, ceramic plastic body, tourmaline or from a crystal which contains chitosan. 
     
     
         5 . The chair of  claim 1 , wherein the first backrest returns to an original position from a rotated position by a first elastic member which is connected to the first backrest rotational axis, and wherein, the second backrest returns to an original position from a rotated position by a second elastic member which is connected to the second backrest rotational axis. 
     
     
         6 . The chair of  claim 1 , further comprising neck massage members coupled to one end portion of the first backrest rotational axis that is extended in an upward direction, and to one end portion of the second backrest rotational axis that is extended in an upward direction, and wherein, the neck massager members rotate while the first backrest and the second backrest rotate.
