Abstract: A seat slide device includes a reinforcing member attached to a rear end part of an upper rail. The reinforcing member is higher in rigidity than the upper rail. The reinforcing member includes a reinforcing member body having a U-shaped cross section having a lower opening, and including a reinforcing member top wall; a pair of reinforcing member lateral walls; and a pair of reinforcing member bent wall parts each being bent outwardly from a lower end of a corresponding one of the reinforcing member lateral walls in a lateral direction of the reinforcing member, and extending upwardly between a corresponding lower rail outside lateral wall and a corresponding lower rail inside lateral wall.

Abstract: A massage unit includes a base member, a treatment element driven unit, and a slide mechanism. A lower portion of the treatment element drive unit is fitted to the base member to be rotatable about a first rotation axis. One end of the slide mechanism is fitted to a lower portion of the base member. The other end of the slide mechanism is fitted to the treatment element drive unit. At least one of the following structures is adopted: a structure where the one end of the slide mechanism is fitted to a lower portion of the base member to be rotatable about a second rotation axis; and a structure where the other end of the slide mechanism is fitted to the treatment element drive unit to be rotatable about a third rotation axis.

Abstract: It is a primary object of the present invention to provide a massage unit and a massage machine which can increase a protruding amount of a massage ball. A massage unit 700 includes a pair of massage elements 350; a forward-backward axis 722 forming a swinging fulcrum point for moving the pair of massage elements 350 toward a body of a person to be treated; and an up-and-down axis 732 for moving the massage unit, wherein the forward-backward axis 722 is formed in parallel with the up-and-down axis 732 and provided nearer to the side of the body of the person to be treated than the up-and-down axis 732.

Abstract: In a seat slide device applicable to an automotive vehicle, a lock mechanism includes: a lock arm disposed on an upper rail to be pivotable around a pivotal center axis; lock pawls formed on the lock arm along the elongate direction of the upper rail; lock holes formed on a lower rail and the upper rail, the lock pawls being inserted through the lock holes to lock the upper rail with respect to the lower rail; a pair of slits formed at predetermined front-and-rear positions of a side surface of the upper rail; and a bearing bracket, the bearing bracket and the lock arm being disposed within an enclosed space between the upper rail and the lower rail and including a pair of bearing portions and both ends of the lock arm and the pair of bearing portions being disposed within inner spaces defined by the pair of slits.

Abstract: A seat slide apparatus for a vehicle includes: a lower rail; an upper rail; a lock arm including lock claws; a memory rail including engagement grooves; a memory base including an engagement member; a lock release lever; and a connection separation lever. The lock claws are arranged to be engaged or disengaged with the lock holes at a position other than a position at which the engagement portion is engaged with the one of the engagement grooves. The upper rail includes a pushing portion arranged to push the engagement member when the upper rail is moved in the forward direction of the vehicle at the release state between the upper rail and the memory base, and to move the memory base at the position at which the engagement portion is engaged with the one of the engagement grooves.
