Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention mainly relates to a plug-in headrest for a vehicle that is incorporated into a seat bag of an automobile.

(Prior art) A tilting type headrest for a vehicle that is a plug-in type vehicle headrest attached to the top of a seat bag, which allows the headrest body to be tilted forward or backward when not in use to improve visibility, was developed in the Showa period. This method has already been proposed in Publication No. 59-14530. However, the vehicle headrest described in the above-mentioned publication has a headrest support tube inserted into the top of the seat bag with a foldable support leg hanging vertically from the headrest body, which is slidably inserted and held therein. When not in use, when the headrest body is pulled up until the folding joints of its support legs are positioned above the upper end of the headrest support tube, the headrest body can be folded forward or backward from the folding joints. ing.

(Problem to be solved by the invention) For this reason, although conventional vehicle headrests can improve visibility by tilting the headrest body forward or backward when not in use, the folding joint supports the headrest. The tube is exposed slightly above the upper end of the tube, which is not only unsightly, but also the exposed folding joint may injure the passenger's body, which poses problems in terms of decoration and safety, and the structure is complicated. It was hot.

(Means for Solving the Problems) A vehicle headrest of the present invention which attempts to solve the above-mentioned problems includes a narrow recessed notch that is opened from one side to the top of the seat bag in the upper part of the seat bag. A tubular head rest support having a notch for hook intervention formed on the upper side surface is provided in the recessed part so as to be able to rise and fall freely, and a spring is provided to constantly pull the head rest support in the direction of falling down. A headrest main body, which is provided with a plurality of engagement notches to be combined with the notches on the side surfaces of the support legs, is slidably inserted into the headrest support by holding the support legs, and a headrest main body is slidably inserted into the headrest support by holding the support legs. From a normal state in which the hook engages with and disengages from the headrest support by operating an operating lever, and the hook engages with a required engagement notch through the notch to hold the headrest support upright; A state in which the height of the headrest body can be adjusted while the headrest support is held upright without being engaged with the engagement notch, and a state in which the headrest body is disengaged from the headrest support and is laid down. It is characterized by being able to be switched.

(Function) This type of headrest for a vehicle normally maintains a normal state in which the headrest body is located above the top of the seat bag, and has a stable head support function, but when not in use when no one is seated. When you want to improve your visibility at times, etc., you can release the engagement and retention of the headrest support by the engagement and disengagement retention mechanism by operating the operating lever, and the elastic force of the spring moves the headrest body, which can rise and fall freely within the narrow recessed part. This automatically tilts the headrest forward and eliminates the headrest body from above the seatback, ensuring visibility. In addition, when you want to adjust the height of the headrest, the hook of the engagement/disengagement holding mechanism engages and holds the headrest support in its normal position, and the support legs of the headrest body can be slid freely relative to the headrest support by operating the operating lever. You can adjust the height as follows.

(Embodiments) Next, the present invention will be described in detail with reference to illustrated embodiments.

Reference numeral 1 denotes a seat bag with a built-in support frame 2, and the upper half of the seat bag 1 is provided with a narrow recessed part 3 that is opened from the front of the seat bag 1 to the first half of the upper surface at a required interval. 2 after
Individually arranged. Reference numeral 4 denotes a headrest which is mounted in each recessed notch 3 with both legs so as to be able to rise and fall freely.
The head rest main body 5 includes a head rest support 6 having a tubular shape. The headrest support 6, which is erected up and down in each recessed notch 3, has its lower end pivotally supported by the intermediate member 2b of the support frame 2 with a shaft 8, and the upper end of the headrest support 6 is It is located slightly above the top side 2a of the support frame 2, and when the headrest support 6 is erected, its upper part comes into contact with the receiving groove 7 provided in the top side 2a. There is. The headrest main body 5 is slidably inserted into the headrest support 6 with support legs 5b, 5b.
Reference numeral 9 denotes a spring that constantly pulls the headrest support 6 in the downward direction within the seat bag 1, and in the embodiment, it is stretched between the lower part of the headrest support 6 and the arm portion 2c of the intermediate member 2b. Reference numeral 13 denotes an engagement/disengagement holding mechanism provided at the top of the seat bag 1, and the engagement/disengagement/holding mechanism 13 has an upper portion that holds each headrest support 6 in the receiving groove 7 provided on the top side 2a of the support frame 2 during normal operation. Although the headrest 4 is held in an upright state by being locked by the hook 14,
Operation lever 1 exposed rearward from cover 15
When 6 is operated, hook 14 is connected via link 17.
The locking of the headrest support 6 is released,
The headrest 4 can now pivot forward,
Further, this engagement/disengagement holding mechanism 13 also serves as a height adjustment mechanism for the headrest main body 5. That is, a notch 10 is provided on the side surface of the upper part of the headrest support 6 where the hook 14 comes into contact with which the hook 14 is brought into contact, and the operating lever 16 is operated in a two-stage manner, so that the hook 14 is normally operated.
enters into the headrest support 6 through the notch 10 and engages with a required engagement notch 11 provided in the support leg 5b to maintain the height of the headrest main body 5 at a constant position and the headrest support. 6 is held in an upright position, but when the first lever is operated, the hook 14 is positioned outside the notch 10 and only holds the headrest support 6, and the height of the headrest body 5 can be freely adjusted. Only when the second stage lever is operated, the locking of the hook 14 to the headrest support 6 is released and the headrest 4 is tilted forward by the traction force of the spring 9. In the embodiment described above, the recessed portion 3 is located on the front surface of the seat back 1 since it is for a rear seat, but it may be located on the rear surface in a case where the seat back is used for a front seat.

This structure maintains a normal state in which the pillow-shaped head 5a of the headrest 4 is always located above the top of the seat back 1, and has a stable head support function. If you want to improve visibility when not in use with no one seated, operate the operating lever 16 to release the hook 14.
When the headrest support 6 is released from the locking position, the headrest support 6 is constantly pulled in the direction of lying down by the spring 9, so the headrest 4 in the recessed part 3 automatically falls down and moves forward. The pillow-shaped head 5a of the headrest 4, which is extended above the top of the seat bag 1, is located in front of the seat bag 1, so that visibility from the rear seat can be ensured. If you want to return the headrest 4 to its old state, then press the headrest main body 5 with the spring 9.
All you have to do is to stand up against the elastic force of , and then follow the steps in reverse to the above steps. Therefore, when it is desired to adjust the height of the headrest body 5, the headrest body 5 is slidably pushed into the headrest support 6 with its supporting legs 5b, and the headrest body 5 is slidably pushed into the headrest support 6 with its supporting legs 5b. A plurality of engagement notches 11 are arranged to be combined with the notches 10 on the upper side of the headrest support 6, and the headrest support 6 is held in an upright state against the elastic force of the spring 9. The hook 14 of the mechanism 13 is engaged with the required engagement notch 11 through the notch 10 by operating the operating lever 16, and is not engaged with the engagement notch 11 from the normal state in which the headrest support 6 is held upright. Since the head rest support 6 can be freely switched to the state where it is held upright, the support leg 5b can be freely slid against the head rest support 6 by operating the operating lever 16 while the head rest support 6 is held upright. The height can be easily adjusted.

(Effect of the invention) As is clear from the above description, the present invention allows the legs of the headrest to be raised and lowered freely within the narrow recess provided in the upper part of the seat bag, so that the headrest can be lowered to improve visibility. Compared to conventional seats, in which the folded part protrudes from the top of the seat back when folded down, it looks better, and there is no risk of the occupant's body being injured by touching the folded part, which is preferable from both a decorative and safety standpoint. In addition, once the headrest support is unlocked by the locking/disengaging holding mechanism, the work of lowering the headrest is automatically done by the traction force of the spring, which has the advantage of easy operation. The legs can be slid and fixed to the headrest support, and the height of the headrest can be easily adjusted by operating the operating lever of the locking/disengaging mechanism. It has great practical value as it solves the problems of vehicle headrests.
