New description: [New technical field] This case is related to the wheelchair «, more detailed (4), the age-aged wheelchair is used to support the head and neck of the user. [Prior Art] A general wheelchair structure is generally constructed of a light seat surface, a cloth backrest, a rear push handle, a left and right armrest, a rear wheel set, a group, and a pedal. The height of the above-mentioned cloth backrest is for the general wheelchair to rely on (4) to rely on, and the ability to record the ship’s wealth is unsatisfactory, but it has the ability to stand up, and the height of the wheelchair is sufficient for the user. Use a wheelchair in a good sitting position. The general wheelchair does not have a job structure, that is, the wheelchair person needs to have sufficient force or the muscle strength of the neck and shoulder to support the head, but the wheelchair maker Lin-Jinna holds such a good condition and is suitable for the body. , physical strength or the need for paste parts _ support for the new material, should be timely added to the wheelchair headrest structure. [New content] The main purpose of the case is to provide a headrest structure for a wheelchair, which is characterized by a simple hand _ Yu Qing ft_pT. _ face μ, green chair makes _ head and neck get support. The structure of the headrest of a wheelchair mainly includes: the branching wood has an arm pivoting portion on the left and right sides of the main bracket, and a pillow pole pivoting portion in the center; the whole length of the private 'every arm of the arm is _ The movable end is pivotally connected to the above-mentioned arm pivoting 5 M323893 a pair of fixing seats, each of which is disposed at an open end of the arm, the fixing seat can be fixed to a push handle of a wheelchair, a pillow group, and one end of the pivot The bolster pivot portion of the main bracket is movably movable in the bolster pivot portion and can be fixed at an intended position, and the other end of the bolster group is provided with a cushion. The case is mainly to establish a headrest structure at the push handle of the wheelchair, and the headrest structure of the headrest can be moved up and down, and the position is adjusted back and forth, so that the headrest can securely support the head and neck of the wheelchair user. . The headrest structure of the present case can adjust the span of the wheelchair according to the distance of the pusher, so that the fixed seat to which it belongs can be fixed to the second pusher of the wheelchair. When the headrest structure of this case is in a secret wheelchair, it can be folded in a manner that reduces the width of the left and right. [Embodiment] As shown in the first and second figures, the headrest structure of the wheelchair of the present invention mainly comprises: a main bracket 10, the main bracket 1G has a -f lever pivoting w, and the towel center is a pillow pole pivoting portion 12. The arm pivoting portion u is a top open accommodating lang in the drawing. The bolster pivotal portion 12 is a longitudinally-oriented, and the main support_bottom is provided to extend the length of the hole. The pair of rods 20, each arm of the arm is axially relatively pivoted by the - - - - - - - - - - - - - - - - The end of the first rod member 21 is pivotally connected to the above-mentioned (four) rod pivoting portion u, and can be rotated by 23 as an axis. The second rod member 22 is movable in the first rod member , to vary the length extending beyond the first rod member 21. The first pole is set to - (4) Yuan Lai, when the element is locked, the second rod can be used to provide a radial pressing force to make the gorge in the intended position. The open end of the second rod member 22 of the mouthpiece 3G 'cake' is fixed to the pusher 91 of the wheel by the fixing fine, as shown in the ninth figure. The second dirty open end turn M323893 extends in a horizontal section 221, and a circular tubular pivoting section 222 is disposed at the open end of the horizontal section 221, so that the fixed seat 30 is pivoted by the pivoting portion 31 thereof. Moreover, the pivoting section 222 can be freely rotated as a center. The pivoting portion 31 of the fixing base 30 is a push rod fitting portion 32 below, and a circular arc-shaped fitting space 33 is provided inside to fit the bending portion of the wheelchair 9 〇 pusher 91, and The bolt 34 is locked and the wheelchair pusher is restrained in the pusher sleeve portion 32. The bolster set 40 includes a pillow upright 41 and a occipital crossbar 42 pivotally inserted into the bolster pivotal portion 12 of the main bracket 10, the apex apex intersecting perpendicularly The piercing portion 43 is provided with a tubular cross-section for her to wear. The sleeper bar & and the sleeper bar 42 are movable along a bolster pivot portion 12 and a threaded shaft _ which are matched thereto, and the bolster pivot portion (10) and the wear contact are respectively provided with a fastening 兀The members 14, 44 can provide a radial pressing force to the pillow upright 41 and the sleeper bar 42 when the fastening elements 14, 44 are locked, so that the sleeper bar 42 and the pillow stand are fixed to - intended location. - Pillow 5G, the shop is connected to the above-mentioned pillow-slave end by a universal joint. The headrest 5 〇 has a keeper-hunting portion 53, which is half-shaped, and provides support for the left and right parts of the user's head and neck to prevent head and neck from skewing. In the present case, the pillow crossbar 42 and the wearing contact, the pillow upright 41 and the bolster pivotal portion 12, and the first and second members 21 and 22 of the arm are all recorded by means of a polygon. Can't turn each other. The fixed hinges 14, 44 are all free and easy to handle. According to the third and fourth figures, according to the above structure of the present case, the fastening element 〇 on the main bracket ι can be loosened, so that the mast can be recorded __, _5 () to - New height, and then rotated The fastening element 14 can be tightened. As shown in the fifth and sixth figures, the fastening member 44 on the insertion portion 43 is loosened, i.e., the pillow rail can be moved at the insertion portion to adjust the front and rear positions of the pillow 5g. Adjust the height of the back and the front and rear position to support the head of the wheelchair and talk. In addition, since the M323893 headrest 50 is coupled to the sleeper bar 42 by the universal joint 51, the headrest 50 can be tilted up or left and right to adjust the angle. As shown in the fifth and sixth figures, the fastening member 24 of the arm 20 can be loosened to move the second rod member 22 in the first rod member 21 to change the length extending beyond the first rod member 21, This will change the span of the two booms 20 as the span L1 of the sixth figure is greater than the span L2 of the fifth figure and the relative distance of the two mounts 3〇 so as to correspond to the relative width of the wheelchair 90 pusher 91. The fixing seat 3 is fixed to the pusher 91. Because the above-mentioned fixing seat 30 can be rotated by the pivoting section 222 of the second rod 22, regardless of the extension length of the second rod 22, the span of the arm 20, the two fixing bases 30 can still be held perpendicular to the position of the wheelchair 9 〇 pusher 91 corresponding to the pusher 91, as shown in the seventh figure. As shown in the eighth figure, the headrest structure of the present case can be folded after being disengaged from the wheelchair, because the above-mentioned arm pivoting portion 11 is a receiving space with a top open space, so the two-armed rod can be used for the tip. 23 is rotated upwards for the axis. The Philippine joint is on the left and right of the pillow upright 41, and the width of the structure of the case is reduced according to the seam, so that it is easy to store. Although the case is paid for by the best one, the skilled person can make various (four) forms of change in the spirit of the unjustified case. The above-mentioned actual side is based on the case, and is not used to limit the supplement of this case. Any modification or change of the hybrid that does not violate the spirit of the case is the scope of application for patent in this case.
