Description

[Detailed Description of the Invention] The present invention relates to a seat height adjustment position confirmation device that can confirm the appropriate height when adjusting the vertical height of a vehicle seat.

The height of the vehicle seat surface on which a passenger sits from the vehicle floor is designed based on the average value of the human body, and therefore does not necessarily match each body type.

Therefore, depending on the vehicle type, a seat vertical height adjustment device is provided.

However, although it seems simple to adjust this height adjustment device, it is not easy, and there are inconveniences such as once the passenger adjusts the height to the appropriate height, and then feels unwell when driving and has to readjust it. Ta.

In this case, if there is a guideline that the height should be adjusted to this position, the above-mentioned problem will be resolved and the height can be adjusted appropriately so that a comfortable driving position without feeling fatigue can be achieved from the beginning.

This invention is proposed to meet this demand,
It is an object of the present invention to provide a height adjustment position confirmation device that has a simple configuration and can easily adjust the seat height to suit the body shape of each person.

In other words, the present invention provides a seat vertical height adjustment device that is adjusted by an adjustment member and a link mechanism, which is rotatably supported by a member fixed to a seat cushion frame so as not to move in the axial direction, and has a threaded portion. a nut screwed onto the threaded portion and moved in the axial direction when the adjusting member does not rotate; one end pivotally connected to the nut and the other end the link. A link member that is pivotally supported by a member of the mechanism and moves in the axial direction together with the nut, and a moving member such as the link member, the nut, and the adjustment member, or a seat bracket that is fixed to the seat cushion frame and protrudes from the link member. A seat height adjustment position confirmation device comprising: an engaging member provided; and an elastic member attached to the other of the movable member or the seat bracket and producing soundproofing when in contact with the engaging member. be.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Figure 1 is a side view showing the outline of the configuration of the present invention, and Figure 2 is a side view showing the outline of the configuration of the present invention.
FIG. 3 is an enlarged perspective view of part A in the figure, and FIG. 3 is a perspective view showing another example of the notification sound generating section.

In FIGS. 1 and 2, reference numeral 1 denotes a handle attached to a shaft 2, and an adjusting rod 4 having a threaded portion 5 cut therein is connected to the front of the shaft 2 by a spring pin 3.

This shaft 2 and adjustment rod 4 constitute an adjustment member.

On the other hand, at one end of the link member 7, a female threaded nut 6 which is screwed into the threaded portion 5 is rotatably installed, and its pin portion 6b projects to the side of the link member 7.

The nut 6 and the pin portion 6b may be separate bodies.

This pin portion 6b constitutes an engaging member.

Further, the leaf spring 8 having the tongue piece 8b bent downward is fixed to the front cushion frame 11.

The tongue piece 8b is attached to the seat bracket 10 with machine screws 9 so as to come into contact with the pin part 6b.

The leaf spring 8 having the tongue piece 8b constitutes an elastic member.

As long as the attachment using the machine screws 9 is reliable, it is acceptable to use only one screw.

Now, if you turn the handle 1 clockwise, the link member 7 will move in the direction of the solid line arrow, and if you turn it in the opposite direction, it will move in the direction of the dotted line arrow, and the pin part 6b protruding from the link member 7 will hit the tongue piece 8b. Since the piece 8b bends and makes a snapping sound, the operator uses this as a guide to know that the adjustment position is appropriate.

By appropriately changing the mounting position of the leaf spring 8 provided with this tongue piece 8b, it is possible to know the appropriate adjustment position.Also, it is possible to know whether the number of leaf springs 8 is increased or the specifications of the leaf spring 8 are further changed. Alternatively, the adjustment position can be notified in various ways, such as by using a piano wire to change the tone and tone of the generated sound, or only the pin portion 6b may be added to the link member 7 and attached.

FIG. 3 shows a modification of FIG. 2, in which a pin 12 is provided on the shaft 2, and a bracket 13 with an L-shaped leaf spring 8 attached using machine screws 9 is fixed to the seat bracket 10 of FIGS. 1 and 2.

In this embodiment, the leaf spring 8 generates one sound every time the shaft 2 is rotated once by the handle 1.

Therefore, if you know how many times the sound is emitted to adjust the height, you can easily set it to the correct position.

In this case, it is also good to provide an extra pin 12 on the opposite side by changing the tone.

By adopting the above-mentioned adjustment position confirmation device of the present invention, it is possible to know the height adjustment position that is suitable for each person, and it is possible to drive comfortably without readjusting after sitting and driving, and the configuration is simple. Therefore, it does not break down and can be provided at low cost.
