  • Publication number: 20120157898
    Abstract: Provided is a massager which enables armrests to be used effectively even with a backrest in a reclined state. The massager includes: a backrest having a massaging mechanism for massaging the back of a user; a frame which supports the backrest in such a manner that the backrest can be reclined backwards; a pair of armrests which extend forward respectively from left and right side positions of the backrest; and a linking mechanism which changes an attitude of the pair of armrests in conjunction with a reclining operation of the backrest, in such a manner that a rear part of each armrest falls lower than the front part of each armrest, when the backrest is reclined backward.

  • Patent number: 7789466
    Abstract: A chair-type massage machine includes a seat on which a user sits; a leg rest whose one end portion is pivotally connected with a front portion of the seat for pivotal movement up and down, the leg rest supporting calves of the user; a driving unit for pivotally moving the leg rest with respect to the seat; a footrest pivotally connected with the other end portion of the leg rest for pivotal movement up and down, the footrest supporting feet of the user; and a massage means provided to at least one of the leg rest and the footrest. Also, a stopper unit is provided for restricting a pivotal movement range of the footrest with respect to the leg rest, and a biasing unit is disposed for applying a biasing force to the footrest in either an upward or downward a direction of the pivotal movement.
