The gear set part 100 carries a function of transmitting a driving force by a motor 2 capable of providing a massage to a passenger. The gear set part 100 may have various structures. However, The pinion gear 120, the ring gear 110, and the sector gear 140 as shown in the figure so as to be applicable to other types of vehicles due to simplification.

However, the coupling relationship and the working relationship between the specific configurations will be described later.

Meanwhile, a drive transmission unit 200 is provided which performs a massage function while moving in the forward and backward directions by the driving force transmitted by the gear set unit 100.

As shown in the drawing, the drive transmission unit 200 is positioned above the gear set unit 100 and is configured to slide in the forward and backward directions by the driving force of the motor 2. In the drawing, the gear set unit 100 is disposed at the lower side The drive transmission portion 200 is located on the upper side, but the positions thereof can be changed with each other, and their respective positions can be changed according to the designer's intention.

The elastic member 400 is provided at the rear end of the drive transmission unit 200. When the drive transmission unit 200 is moved backward, the drive transmission unit 200 is forwardly moved by the elastic force stored therein, Function.

That is, the power by the motor is transmitted to the drive transmitting portion 200 through the gear set portion 100, and the pressure receiving portion 300 located in front of the drive transmitting portion 200 is moved forward to provide the driver with a massage function The length of the restoring spring constituting the elastic part 400 is increased and returned to the original position by the operation of the gear set part 100. Thereafter, the elastic pressing part 300 moves forward Massage function is performed.

The gear set part 100 capable of performing the massage function through the reciprocating motion of the pressure applying tool 300 will be described in detail as follows.

1, the gear set portion 100 includes a pinion gear 120 coupled to a rotation shaft of a motor 2, a ring gear 110 and a ring gear 110 that are rotated to mesh with the pinion gear 120, And a sector gear 140 rotatably coupled to the intermediate gear 130 and gear teeth 141 formed on only part of the circumferential surface of the intermediate gear 130 and the intermediate gear 130, .

4, the rotation shaft of the motor 20 is coupled to the pinion gear 120, and the ring gear 110 is rotatably engaged with the pinion gear 120 when the pinion gear 120 rotates.

Needless to say, the pinion gear 120 and the ring gear 110 are examples of the present invention, and a bevel gear may be employed if the motor 20 is capable of transmitting power.

An intermediate gear 130 that rotates when the ring gear 110 rotates is provided and a first thread 131 (not shown in the figure) Is provided in the intermediate gear 130. [

Of course, if the intermediate gear 130 is also capable of transmitting the power, it is obvious that a so-called " spur gear "

The power transmitted to the intermediate gear 130 is transmitted to the sector gear 140. The sector gear 140 includes a second screw thread 142 meshed with the first screw thread 131 formed on the intermediate gear 130, And a gear tooth 141 which is larger than the projecting height of the second screw thread 142 is formed on a part of the circumferential surface.

The gear teeth 141 formed on the sector gear are engaged with the bar gears 140 formed on a part of the circumferential surface of the gear teeth 141. [ The slider 210 does not move as well.

That is, the slider 210 is moved backward only when the gear teeth 141 formed on the sector gear are coupled with the threads 220 formed at the lower end of the slider 210, and the sector gear 140 When the gear teeth 141 are out of the gear teeth 141 formed at the lower end of the slider 210, the slides are moved forward again by the elastic part 400 described above.

2, when the sector gear 140 rotates in the clockwise direction, the slider 210 is also moved rearward, and when the sector gear 140 rotates clockwise, the elastic part 400 moves The spring of the predetermined length is compressed.

2 (c), when the gear teeth 141 formed in the sector gear 140 move out of the thread 220 formed at the lower end of the slider 210, as shown in FIG. 5D, the massage is performed by hitting the back portion of the passenger while moving forward.

As shown in FIGS. 1 and 2, the drive transmission unit 200 includes a cylindrical gear 220 coupled to the gear teeth 141 formed in the sector gear, And a slider (210).

Of course, the shape of the drive transmission unit 200 may be variously changed according to the designer, but it is preferable that the drive transmission unit 200 is formed in a cylindrical shape that continuously reciprocates in the forward and backward direction and minimizes the frictional force.

The gear teeth 141 may be formed on the sector gear 140 and the threads 220 may be formed on the lower end of the slider 210. The gear teeth 141 may be formed on the sector gear 140, Alternatively, a protruding groove having a predetermined height may be provided, and a guide groove through which the protruding groove can move may be provided at the lower end of the drive transmitting portion 200.

1 and 2, the pressure member 300 and the damper 500, which are components of the present invention, will be described below.

One end of the acupressure tool 300 is inserted into a first epilating hole 310 formed at the center of the slider 210 in the longitudinal direction thereof and is moved in the forward and backward directions in cooperation with the slider 210 to provide a massage function to the occupant, A damper 500 is provided between the rear end of the pressure applying tool 300 and the front end of the slider 210 so as to absorb a shock due to vibration.

That is, as shown in the figure, an annular damper 500 is installed to absorb the shock caused by the continuous reciprocating motion, thereby ensuring durability.

1 and 2, the elastic part 400 includes a support 600 and a support 600 which are fitted in a second elastic hole 320 formed at the center of the slider 210 in the longitudinal direction thereof, And one end thereof is coupled to the guide 700 and the other end thereof is connected to the guide 700.

That is, one end of the support member 600 is inserted into the second elastic hole 320 formed at the center of the slider 210 and inserted into the second elastic hole 320, and moves in the forward and backward direction while interlocking with the slider 210, A restoration spring having a predetermined length is provided between the guide 700 and the restoring spring is also compressed or elongated according to the movement of the slider 210 in the forward and backward directions.

An upper housing 800 provided with a drive transmission portion 200 and an elastic portion 400 therein and a motor and a gear set portion 100 are installed in the lower housing 800, And a lower housing 900 provided in communication with the lower housing 900.

The upper housing 800 and the lower housing 900 perform a casing function and the upper housing 800 protrudes forward by a predetermined length as compared with the lower housing 900 as shown in FIG.

3, the lower housing 900 is installed at the rear of the frame, and the upper housing 800 passes through the frame at a predetermined depth, .

This structure provides the driver with a more stable massage function.

The guide groove 211 protrudes at a predetermined height from both sides of the slider 210 and is formed in the longitudinal direction of the slider 210. A guide groove 211 is formed on both inner sides of the upper housing 800, And a guide slot 212 of the guide plate 212 is provided.

That is, by providing the guide groove 211 and the guide slot 212, it is possible to smoothly perform the reciprocating motion, thereby maximizing the massage function. In order to restrict the movement of the slider 210, A stopper 910 having a cross section corresponding to that of the damper 500 is installed between the pressure applying member 300 and the damper 500. This prevents the slider 210 and the damper 500 from falling out from the inside of the upper housing 800, It is for this reason.
