Definitions

  • the present invention relates to a massage device, and more specifically, to a massage device having a rotatable arm massage part for massaging a user's arm area, and an angle-adjustable massage device capable of adjusting the angle of the seat and backrest of the massage device to a desired angle when the user stands up from the massage device after using the massage device, sits down to use the massage device, or sits on the massage device.
  • Massage is a medical auxiliary therapy that regulates the body's tone, helps blood circulation, and relieves fatigue by applying various forms of mechanical stimulation to parts of the body, such as kneading, pressing, pulling, tapping, or moving the body.
  • Japanese Patent Application Laid-Open No. 2015-027424 discloses a massage device including an arm massage unit.
  • existing massage devices have various angle adjustment functions such as allowing the user to receive a massage in a comfortable position by having the backrest rotate forward and backward while the seat is fixed, or allowing the user to adjust the seating angle by having the seat and backrest rotate together.
  • the seat portion of the massage device is configured to rotate upward while the backrest portion rotates downward, enabling a reclining function that allows the user to receive a massage in a nearly lying position.
  • the angle adjustment range of the massage device can be further increased.
  • a large number of actuators must be provided to increase the angle adjustment range, which complicates the overall configuration of the massage device and increases the manufacturing cost.
  • the problem to be solved by the present invention is to provide a massage device that can provide various functions to a user, including a rotatable arm massage part.
  • the problem to be solved by the present invention is to provide a massage device that can simplify the configuration for rotational driving of an arm massage part and minimize the space occupied by the configuration.
  • Another problem to be solved by the present invention is to provide a massage device capable of adjusting the angle of the body massage part to any desired angle from an angle at which the user can easily sit or stand up to a reclining angle.
  • the problems to be solved by the present invention are not limited to the problems described above, and include problems that can be easily understood by a person having ordinary knowledge in the technical field to which the present invention belongs from this specification and the attached drawings.
