Abstract

(57) [Abstract] [Purpose] To provide a seat knob structure capable of preventing the occurrence of backlash without impairing operability. [Structure] The knob 5 has a small-diameter portion 8 into which an eyelet 6 fitted into the seat back 2 is fitted, a step portion 10 in close contact with the eyelet 6 and a length dimension at which the knob 5 can be gripped by being connected to the step portion 10. It has a large diameter portion 9 having. Since the step portion 10 is in close contact with the eyelet 6, there is no backlash.
Since the step portion 10 is located in the middle of the knob 5, the large diameter portion 9 can be extended by that amount and the large diameter portion 9 can be easily gripped. Therefore, the operability is excellent.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a seat knob structure applied to an automobile in which a seat is tiltably provided with respect to a vehicle body.

[0002]

[Prior Art]

 In an automobile, for example, a seat back 2 of a rear seat 1 is tiltably provided as shown in FIGS. 3 and 5, and a knob 5 in which a lock rod 4 is connected to a hole 3 provided in the seat back 2 is provided so as to be vertically movable. There is. In this vehicle, by pulling up the knob 5, the lock mechanism (not shown) provided on the lock rod 4 is unlocked via the lock rod 4 and the seat back 2 is tilted forward from a substantially upright state. It is set to be approximately horizontal so that the cargo space can be expanded.

By the way, an eyelet 6 is fitted between the knob 5 and the seat back 2, but the knob 5 has an insertion portion (from the upper surface of the eyelet 6 to the lower end portion of the knob 5 as shown in FIG. 3). Since the length b) is shallow, a gap is easily formed between the eyelet 6 and the knob 5, and play is likely to occur. In FIG. 3, 2a is a urethane seat main pad and 2b is a seat cover pad.

As another example of a conventional seat knob structure, as shown in Japanese Utility Model Laid-Open No. 57-69723, a rod provided with a flange-shaped protrusion for positioning the operation knob is assembled by screwing. Although there is an operation knob of the type that has been set, this operation knob can also solve the problem that when it is inserted into the hole of the seat back, a gap is created between the eyelet and the backlash as described above. It wasn't something.

There is a device shown in FIG. 4 as a device for preventing such play. The knob 5 shown in FIG. 4 is configured such that the upper end portion 7 of the knob 5 is inserted into the hole 3 of the seat back 2. With this configuration, the adhesion with the eyelet 6 is secured, and at the same time, By setting the insertion portion b to be long, it is possible to prevent play.

[0006]

[Problems to be solved by the device]

 By the way, in the above-described seat knob structure, there is a problem in that the length of the insertion portion b lengthens the portion a to be gripped by hand, and the operability is impaired.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a seat knob structure capable of preventing the occurrence of backlash without impairing operability.

[0008]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention provides a seat back tiltably with respect to a vehicle body, and operates a locking device of the seat back by operating a knob provided vertically movable with respect to the seat back. In the vehicle described above, the knob has a small-diameter portion into which the eyelet fitted into the seat back is inserted, a stepped portion that is in close contact with the eyelet, and a large dimension that is connected to the stepped portion and can be gripped. It is characterized in that it is composed of a diameter part.

[0009]

[Action]

 With such a configuration, the step portion comes into close contact with the eyelet, so that there is no backlash. Further, since the step portion is located in the middle of the knob, the large diameter portion can be extended by that amount and the large diameter portion can be easily gripped.

[0010]

【Example】

 Hereinafter, an embodiment of the present invention will be described with reference to FIGS. 1, 2 and 5. The same members as those shown in FIGS. 3 and 4 are designated by the same reference numerals, and the description thereof will be omitted.

In the figure, the knob 5 is roughly composed of a small diameter portion 8 and a large diameter portion 9 connected to the small diameter portion 8. The small diameter portion 8 is adapted to be fitted with the eyelet 6. The large-diameter portion 9 is formed by forming a step on the small-diameter portion 8, and a step portion 10 formed between the large-diameter portion 8 and the small-diameter portion 8 is in close contact with the eyelet 6.

Since the step portion 10 is located in the middle of the knob 5, the large diameter portion 9 can be set longer by that amount, and the large diameter portion 9 can be easily gripped by setting the large diameter portion 9 longer in this way. It has become.

In the knob structure of the seat configured as described above, since the step portion 10 is in close contact with the eyelet 6, there is no backlash. By setting the large-diameter portion 9 to be long, the large-diameter portion 9 can be easily gripped, so that the operability of the knob 5 becomes excellent. Further, since the eyelet 6 is hidden by the step portion 10, the appearance is excellent.

[0014]

[Effect of the device]

 Since the present invention has the seat knob structure configured as described above, the step portion comes into close contact with the eyelet, so that there is no backlash. By positioning the step portion in the middle of the knob, the large-diameter portion 9 can be set longer by that amount, so that the large-diameter portion can be easily gripped and the operability is excellent.
