Description
BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention relates to a height link drive apparatus for an automobile seat, and more particularly, to a height link drive apparatus for an automobile seat for operating a height link for adjusting the height of a seat cushion in an automotive seat.
Generally, the seat of an automobile has a function of adjusting the angle of the seat back and the position of the seat back and forth for the convenience of passengers.
In addition, as an additional convenience specification, there is an increasing number of vehicles to which the height adjusting device is applied so that the height of the seat cushion can be adjusted.
The seat cushion height adjusting device is composed of a link mechanism interlocked with the height link, and the height link is operated by a height link driving device including a pumping device.
As shown in Fig. 1, the above-mentioned HeightLink drive device includes a sector gear 2 rotatably installed on one side of a base plate 1 on a side surface of a seat cushion, a pumping device (not shown) provided on the other side of the base plate 1, And a pinion gear 3 mounted on an output shaft of the pumping device and meshed with the sector gear 2, and a height link is connected to an
As described above, the output of the pumping device is transmitted through the pinion gear 3 and the sector gear 2. Depending on the engagement state of the pinion gear 3 and the sector gear 2, Receive.
That is, when the distance L between the shafts of the sector gear 2 and the pinion gear 3 is short, the gap between the gears is insufficient, which makes assembly difficult, lowers operational sensibility, , And the inter-gear clearance is excessive when the inter-shaft distance (L) is long, thereby increasing the impact noise.
Therefore, there is a demand for a heights link drive device in which, when assembled, the distance L between the axes of the sector gear 2 and the pinion gear 3 can be easily adjusted to an accurate value.
SUMMARY OF THE INVENTION It is an object of the present invention to provide a height link drive apparatus for a car seat, which can easily and easily adjust the distance between the sector gear and the pinion gear during assembly.
According to an aspect of the present invention, there is provided a pumping device including a base plate, a sector gear rotatably mounted on one side of the base plate, a pumping device mounted on the other side of the base plate, And a housing bracket mounted on one side of the base plate to cover the sector gear and the pinion gear, wherein the housing bracket is mounted on one side of the base plate, And the housing bracket are integrally connected to each other, and the base plate and the housing bracket are formed with inclined portions which are in close contact with each other when assembled to limit the relative position.
The welded bolt is inserted into the bolt hole formed in the base plate and the mounting hole formed in the mounting flange of the pumping device, and the nut is fastened to the end of the welded bolt.
The gear hole and the bolt hole of the base plate are expanded and formed in a slot shape, and the extending direction thereof is a direction parallel to the axis line of the sector gear and the pinion gear.
As the inclination angle of the base plate inclined portion is larger than the inclination angle of the inclined portion of the housing bracket so that the inclined portion of the housing bracket slides along the inclined portion of the base plate as the nut is tightened so that the pumping device and the housing bracket assembly move toward the sector gear, The inter-axis distance is reduced.
The inclined portion of the housing bracket is elastically deformed by a reaction force applied when the nut is fastened, and is brought into surface-contact with the inclined portion of the base plate as a whole.
The inclined portion of the housing bracket may be divided into a plurality of divided pieces.
And a round portion may protrude from the sloped portion of the base plate to some of the plurality of slit pieces.
As described above, according to the present invention, the base plate and the housing bracket are each provided with the inclined portion, and when the housing bracket is assembled to the base plate by the action of these inclined portions, the distance between the axes of the sector gear and the pinion gear is naturally adjusted to an accurate value .
As described above, since the accurate inter-axis distance is formed, the operational sensibility is improved, the hip-link operating force is reduced, and the noise generation is reduced.
Also, since the assembly is progressed in a state where the distance between the shafts is large at the time of assembling, it gradually decreases and finally the accurate value is formed at the end of the assembly, so that the gap between the gears is large at the initial stage of assembling.
Further, in the interaxial distance adjusting operation according to the present invention, there is an advantage that a separate facility is not necessary since it is merely required to tighten the nut.
