Shoulder Gripping & Massaging
With the aid of a massage hand unit with a joint which moves freely like a thumb, a
massaging technique called "Grip/Grasp/Massage/Knead" for gripping and massaging
the muscles of shoulders has been reproduced.
This massaging technique has been reproduced by way of gripping the shoulders from
above while projecting the massage hands greatly together with a massage unit at the
back (maximum projection of massage hands: approx. 160mm).
Operation of Shoulder Gripping & Massaging
There are two large massage hands and two small massage hands at both ends of the
right and left massage arms. The small massage hands have the structure to move freely.
The massage hands move from side to side according to the operation of massage motors.
When the distance between the massage hands becomes narrower (the massage hands
move inwards), the massage hands move so that the clearance between the large
massage hands and the small massage hands becomes narrower.
Operation of shoulder gripping and massaging: Shoulder position is first measured, and
the massage hands project forward greatly only at the shoulder position and "grip and
massage the shoulders".
*The "shoulder gripping and massaging" function does not work on the back or the waist.
