Description

Technical Field

[0001] The utility model relates to the technical field of headrests, in particular to a power headrest assembly with side wings. Background Art

[0002] Chairs, sofas, loveseats, etc., are typically operably associated with headrests to provide a comfortable environment for a user of the chair, sofa, or loveseat by properly supporting the user's head when the user is seated in the chair, sofa, or loveseat. More specifically, chairs, sofas, or loveseats are typically used when a user wants to relax or take a nap. However, conventional chairs, sofas, or loveseats with operably associated headrests have only one centrally located headrest. Therefore, when a user takes a nap, dozes off, or falls asleep, the user's head often tilts to one side or the other, resulting in the user's head not being properly supported, which may cause or contribute to physical problems (e.g., neck or upper back stiffness or other body stiffness or discomfort in the joints or muscle tissue).

[0079] Example 5:

[0080] like Figures 17 and 18As shown, a powered headrest assembly 100 with side wings includes: a basic headrest located in a central position, two secondary headrests, and a driving member. The two secondary headrests are respectively located on both sides of the basic headrest, and the secondary headrests are hingedly connected to the basic headrest. The two ends of the driving member are respectively connected to the basic headrest and the secondary headrests. The driving member is used to drive the secondary headrests to switch back and forth between a folded position and an extended position relative to the basic headrest.

[0081] In this embodiment, the driving member includes: two sub-driving members; the sub-driving members are linear driving members.

[0082] In this embodiment, the two linear driving members are driven independently, so that the two secondary headrests can be folded or extended independently.

[0083] In this embodiment, the headrest assembly 100 further includes a shell portion, which is used to prevent the headrest fabric material from being entangled with the power headrest assembly 100 with side wings.

[0084] In this embodiment, the drive includes: a pair of linear drive members; the linear drive members are unidirectional drive members.

[0085] In this embodiment, the present invention further comprises a coil spring member, both ends of which are connected to the basic headrest and the secondary headrest respectively, and the coil spring member is used to return the secondary headrest to the extended position when the one-way driving member is deactivated.

[0086] In this embodiment, the basic headrest is the fifth headrest portion 502 , the two secondary headrests are the ninth auxiliary headrest portion 504 and the tenth auxiliary headrest portion 506 , and the coil spring member is the third coil spring 564 .

[0087] Specifically, the ninth auxiliary headrest portion 504 is mounted to the fifth headrest portion 502 through a fifth hinge mechanism 508, and the tenth auxiliary headrest portion 506 is mounted to the fifth headrest portion 502 through another fifth hinge mechanism 508; the linear drive component includes: two fifth linear actuators 510, the fifth linear actuator 510 is a one-way actuator, the third motor end of the fifth linear actuator 510 is mounted on the rear surface of the fifth headrest portion 502 through a third motor mounting bracket 514, and the free end of the fourth telescopic rod 518 of the fifth linear actuator 510 is provided with a roller 572.

[0088] Specifically, one slide plate 524 is mounted to the ninth auxiliary headrest portion 504 via the mounting plate 528, and the other slide plate 524 is mounted to the tenth auxiliary headrest portion 506 via the mounting plate 528. The roller 572 is coupled to the inner surface of the slide plate 524. The first end of the third coil spring 564 is connected to the opposite free end of the slide plate 524, and the second end of the third coil spring 564 is connected to the seventh mounting bracket 574. The seventh mounting bracket 574 is mounted to the rear surface of the fifth headrest portion 502. When the fifth linear actuator 510 is activated, the fourth telescopic rod 518 extends, thereby causing the roller 572 to engage with the inner surface of the slide plate 524. The wheel 572 is coupled to the slide plate 524 and slides on the slide plate 524, thereby causing the ninth auxiliary headrest portion 504 and the tenth auxiliary headrest portion 506 to rotate relative to the fifth headrest portion 502 via the fifth hinge mechanism 508; due to these movements of the slide plate 524, the ninth auxiliary headrest portion 504 and the tenth auxiliary headrest portion 506, the third coil spring 564 will extend; when the fifth linear actuator 510 is deactivated, the third coil spring 564 will return to its non-extended state, effectively pulling the ninth auxiliary headrest portion 504 and the tenth auxiliary headrest portion 506 back to the extended state.

[0089] In summary, the present invention provides secondary headrests on both sides of the basic headrest. When the user's head is tilted while sleeping, dozing or napping, the secondary headrests can support the user's head to improve the user's comfort and effectively prevent neck or upper back stiffness or other body stiffness or discomfort in the joints or muscle tissues.

Based on the above description, relevant personnel can make various changes and modifications without departing from the technical scope of this utility model. The technical scope of this utility model is not limited to the content of the specification and must be determined according to the scope of the claims.
