The disclosure relates to a seating device, and more particularly to a seating device that has an adjustment mechanism for adjustment of a headrest.
A child safety seat is commonly installed in a vehicle for ensuring safety of a child in the vehicle. The child safety seat typically includes a seat base, a backrest part, and a headrest part. Generally, a height-adjusting mechanism is disposed between the backrest part and the headrest part, and an operating device is provided to operate the height-adjusting mechanism for adjustment of the height of the headrest part relative to the backrest part. However, the operating device existing in the prior art is disadvantageous in that it is disposed on the child safety seat in a protruding fashion, and is prone to run the risk of being accidentally touched or pressed, which can lead to undesirable movement of the headrest relative to the backrest and hence adverse effect on safety. In addition, the existing operating device protruding from the child safety seat is not aesthetic.
Therefore, an object of the disclosure is to provide a seating device that can alleviate at least one of the drawbacks of the prior art.
According to the disclosure, a seating device includes a seat body, a headrest, an adjustment mechanism, and an operating unit.
The headrest is movably connected to the seat body. The adjustment mechanism is connected between the seat body and the headrest to adjust a position of the headrest relative to the seat body.
The operating unit is movably mounted to the headrest and has a driving member to actuate the adjustment mechanism, and a handle portion bending from the driving member. The driving member is movable between a non-operative position and an operative position.
When the driving member is in the non-operative position, the handle portion abuts against an outer surface of the headrest.
When the driving member is in the operative position, the handle portion is spaced away and protrudes from the outer surface.
Other features and advantages of the disclosure will become apparent in the following detailed description of the embodiment with reference to the accompanying drawings, of which:
The seat body 4 is mounted on a base 7 and has a backrest portion 41.
The headrest 5 is movably connected to the backrest portion 41 of the seat body 4. As shown in
The adjustment mechanism 6 is connected between the seat body 4 and the headrest 5 to adjust the height or position of the headrest 5 relative to the seat body 4. The adjustment mechanism 6 includes a first locking unit 611 (see
The operating unit 1 is movably mounted to the headrest 5, and has a driving member 11 to actuate the driven member 610, and a handle portion 12 bending from the driving member 11. As shown in
In the non-operative position, the driving member 11 is inoperative to transmit an actuation movement of the handle portion 12 to the driven member 610 of the adjustment mechanism 6. In the operative position, the driving member 11 is operative to transmit the actuation movement to the driven member 610.
As shown in
Each engaging hole 111 is elongated in a top-bottom direction and has a hole boundary. Each engaging pin 614 is slidable along the respective engaging hole 111. The driving member 11 has active transmitting parts 1111, each of which is situated at a bottom side of the hole boundary of the respective engaging hole 111. The driven member 610 has passive transmitting parts 6140 each of which is situated at a bottom side of one of the engaging pin 614 and faces the active transmitting part 1111 of the respective engaging hole 111.
The term “active transmitting part” used herein refers to a part of the driving member 11, at which the actuation movement is delivered to the driven member 610. The term “passive transmitting part” used herein refers to a part of the driven member 610 at which the actuation movement is received by the driven member 610. The active transmitting parts 1111 of the driving member 11 engage the respective passive transmitting parts 6140 of the driven member 610 in the operative position and disengage from the respective passive transmitting parts 6140 in the non-operative position.
Specifically, as shown in
Referring to
As shown in
In the operative position, as the handle portion is spaced away from the outer surface of the headrest 5 against the biasing action of the resilient member 3, handling of the handle portion 12 may be facilitated.
For operating the operating unit 1 to adjust the position of the headrest 5 relative to the seat body 4, the handle portion 12 may be pulled upward away from the top end 5a of the headrest 5. In this situation, the driving member 11 is moved upward so that the engaging pins 614 engage the active transmitting parts 1111 of the hole boundaries of the respective engaging holes 111. Upon continued upward pulling of the handle portion 12, the driven member 610 is moved upward by the driving member 11 so that the tooth engaging shaft 6130 of the second locking unit 613 is uninterlocked with the toothed rack of the first locking unit 611 (see
While the engaging holes 111 are provided in the driving member 11 and the engaging pins 614 are provided in the driven member 610 in this embodiment, according to other embodiments, the engaging holes may be provided in the driven member 610, and the engaging pins may be provided in the driving member 11. In this case, the active transmitting part of the driving member 11 is situated at the top side of the engaging pin, and the passive transmitting part of the driven member 610 is situated at the top side of the engaging hole.
In the description above, for the purposes of explanation, numerous specific details have been set forth in order to provide a thorough understanding of the embodiment. It will be apparent, however, to one skilled in the art, that one or more other embodiments may be practiced without some of these specific details. It should also be appreciated that reference throughout this specification to “one embodiment,” “an embodiment,” an embodiment with an indication of an ordinal number and so forth means that a particular feature, structure, or characteristic may be included in the practice of the disclosure. It should be further appreciated that in the description, various features are sometimes grouped together in a single embodiment, figure, or description thereof for the purpose of streamlining the disclosure and aiding in the understanding of various inventive aspects, and that one or more features or specific details from one embodiment may be practiced together with one or more features or specific details from another embodiment, where appropriate, in the practice of the disclosure.
While the disclosure has been described in connection with what is considered the exemplary embodiment, it is understood that this disclosure is not limited to the disclosed embodiment(s) but is intended to cover various arrangements included within the spirit and scope of the broadest interpretation so as to encompass all such modifications and equivalent arrangements.
