Description

  The present invention relates to a sliding component for a vehicle using a headrest of a vehicle seat as a representative example.

  For example, a headrest of a vehicle seat is provided on the upper side of the seat back frame, in order to equip the headrest main body on the upper side of the seat back, and to insert and hold a headrest stay protruding outside from the headrest main body. .

  Since it is necessary to prevent rattling and abnormal noise during traveling between the headrest stay and the standing tube, measures are taken to reduce the clearance between them. However, if this clearance is reduced, the operation load when raising and lowering the headrest stay increases to adjust the height of the headrest.

  In order to reduce the operation load, a resin coating of silicon resin is applied to the shaft peripheral surface of the headrest stay that protrudes outward from the headrest body, so that lubricity is imparted. However, since the silicone resin is a material that disappears rapidly with the passage of time, the durability of the headrest stay is lacking in terms of providing slipperiness.

  The problem to be solved by the present invention is that the sliding property imparted to the sliding parts for the vehicle is configured to have a high durability, and even if the clearance with the related parts is kept small, the operation load can be reduced, It exists in the place which can be used for a long time as an easy component.

  Claim 1 of the present invention is characterized in that a resin coating of tetrafluoroethylene resin is applied to the sliding surface of the component main body.

  A second aspect of the present invention is characterized in that a resin coating of tetrafluoroethylene resin is applied to a shaft peripheral surface of a headrest stay that projects outward from the headrest body.

  In the sliding part for a vehicle according to claim 1 of the present invention, a resin coating of tetrafluoroethylene resin that has a low coefficient of friction and can withstand long-time use over a wide temperature range is provided on the sliding surface of the part body. Therefore, even if the clearance with the related parts is kept small, the operation load can be reduced and the parts can be used for a long time as easy-to-operate parts.

  In the headrest of the vehicle seat according to the second aspect of the present invention, the resin coating of the tetrafluoroethylene resin having the above-described characteristics is applied to the axial peripheral surface of the headrest stay that protrudes outward from the headrest body. In order to adjust the height, the operation load when moving the headrest stay up and down can be reduced, and the headrest can be used for a long time as a headrest whose position can be easily adjusted up and down.

  FIG. 1 illustrates a seat headrest 1 as a sliding part for a vehicle. The headrest 1 is provided with metal headrest stays 1b and 1c as sliding parts, which protrude outward from the headrest body 1a in order to equip the headrest body 1a on the upper side of the seat back 2. Since the seat back 2 is provided on the upper side of the seat back frame 2a, standing seats 2b and 2c for inserting and holding the headrest stays 1b and 1c are provided.

  In the headrest 1, resin coatings 3a and 3b of tetrafluoroethylene resin are applied to the shaft peripheral surfaces of the headrest stays 1b and 1c protruding outward from the headrest body 1a as shown in FIG. The resin coatings 3a and 3b can be formed by using a fluororesin solution containing, as a main component, tetrafluoroethylene resin (PTFE) and adding fluoro oil and a solvent.

  As shown in FIG. 3, the resin coatings 3a and 3b accommodate the fluororesin solution 4 in the tank of the storage tank 5, and the headrest stays 1b and 1c protruding outward from the headrest body 1a to the fluororesin solution 4 in the tank. It can be formed by applying dipping dipping. If natural drying is performed after this dipping, it can be formed as a film having a thickness of about 3 to 7 μm, preferably.

  In the vehicle seat headrest constructed as described above, the headrest stays 1b and 1c are slid up and down from the standing cylinders 2b and 2c to adjust the height of the headrest 1 above the seat back 2, and the height of the headrest body 1a is adjusted. You only need to set it.

  At this time, since the shaft peripheral surfaces of the headrest stays 1b and 1c are covered with the resin coatings 3a and 3b of tetrafluoroethylene resin having a low friction coefficient, an operating load is applied to move the headrest stays 1b and 1c up and down. The headrest 1 is small and can be easily adjusted in height up and down. Moreover, since the resin coatings 3a and 3b of tetrafluoroethylene resin can withstand long-time use over a wide temperature range, easy operability can be maintained for a long time.

  In the above-described embodiment, the headrest of the vehicle seat has been exemplified and described as a vehicle sliding component. However, in addition to this, the present invention can be applied to a vehicle sliding component such as an operating shaft of a change lever and a bearing base of a door knob. it can.

1 is a front view showing a headrest of a vehicle seat provided on the upper side of a seat back as a representative example of a vehicle sliding component according to the present invention. It is a front view which shows the headrest of FIG. It is explanatory drawing which shows the process of giving the tetrafluoroethylene resin coating of FIG. 2 to a headrest stay.
