[0038] Figure 1 An example seat 20 for an automobile is shown. In this example, the seat 20 includes a seat back 22, a seat base 24, and a headrest 26 mounted on the seat back 22. Although the example seat 20 is for an automobile, it should be understood that the example may be applied to other types of vehicles, such as, but not limited to, motorcycles, buses, boats, gaming chairs, airplanes, or locomotives.
[0039] The headrest 26 includes a core 28 and a support 30 that is pivotally movable relative to the core 28. For example, the core 28 is a fixed portion of the headrest 26, and the support 30 is a movable portion of the headrest 26, and when deployed ( Figure 2) when supporting the nape of the neck of the occupant in the seat. The support member 30 can move within a range M ( Figure 3 ) is manually pivoted. Figure 1 In the embodiment, the support member 30 is in the stowed position, and Figure 2 , the support member 30 is in the deployed position. Figure 3 The range of motion of the support 30 is shown.
[0040] like Figure 4 As shown, the core member 28 includes a core frame 28a and a core foam portion 28b surrounding the core frame 28a, and the support member 30 includes a support member frame 30a and a support member foam portion 30b surrounding the support member frame 30a. The support member frame 30a can be provided as multiple pieces collectively surrounded by the support member foam portion 30b, so that the support member 30 functions as a single piece. For example, the frames 28a and 30a are formed of plastic and provide rigidity and strength to the headrest 26. The core member 28 has a top side T, an opposite bottom side B, a front side F, an opposite rear side R, and opposite lateral sides L1 and L2.
[0041] The core frame 28a includes a lug 34 positioned toward the bottom side B and approximately midway between the lateral sides L1, L2. The core frame 28a and the core foam portion 28b define a pocket 32 ( Figure 3 For example, pocket 32 is a cavity in core 28 that is shaped similarly to at least a portion of support member 30. Pocket 32 extends laterally from one lateral side L1 to the other lateral side L2. In the stowed position, a portion of support member 30 resides in pocket 32, and in the deployed position, support member 30 pivots from pocket 32.
[0042] like Figure 5 As shown, the support member 30 includes a first wing 36 and a second wing 38 and a nape support portion 40 extending between and connecting the wings 36, 38. For example, the wings are side walls, and the nape support portion 40 is the portion of the support member 30 located between the wings 36, 38. The nape support portion 40 is circular to support the nape of the seat occupant's neck. For example, the nape support portion 40 has a vertically rounded frontal surface 40a that faces forward when the support member 30 is in the deployed position. The term "vertically rounded" refers to the curvature of the front surface in the vertical direction, i.e., it is curved in the front-to-back direction. The wings 36, 38 have a larger cross-sectional profile than the nape support portion 40 and are generally located in a plane that is approximately perpendicular to the pivot axis A of the support member 30.
[0043] The lug 34 carries a hinge 35 by which the support 30 is attached to the core 28. The hinge 35 allows the support 30 to pivot about the pivot axis A. For example, Figure 6 As shown, the lug 34 is molded onto a center portion 35a of the hinge 35, and the hinge 35 has two opposing pins 35b (one shown) extending from the center portion 35a onto which the nape support portion 40 is received. By way of example, the hinge 35 is a torque hinge (which is a friction hinge with substantially continuous resistance throughout its range of motion).
[0044] In the stowed position ( Figure 1 ), the nape support portion 40 is received in the pocket 32, and the side wings 36, 38 are substantially flush with the core 28. That is, at least the front and back faces of the wings 36, 38 are flush with the front F and rear R sides of the core 28 (e.g., generally aligned in a common plane). Once moved to the deployed position (i.e., any position where the support 30 is pivoted from the pocket 32), the nape support portion 40 pivots forward and downward out of the pocket 32, and the wings 36, 38 pivot forward and downward in unison to provide sidewall head restraint for the occupant. The support 30 moves as a single piece. Thus, the occupant can easily deploy the support 30 by pulling / pushing on either of the wings 36, 38. As Figure 3 As shown, the wings 36 , 38 are tapered in profile so that the wings 36 , 38 provide a “low profile” to avoid obstructing the occupant’s side view.
[0045] like Figure 7 As shown (see also Figure 6), the headrest 26 also includes a latch 42. The latch 42 is used to define at least one discrete adjustment position within the range of motion M at which the support 30 is retained. For example, the latch 42 includes a tab 42a (e.g., a protrusion) on either the lug 34 or the support 30, and at least one recess 42b (e.g., a depression or indentation similar in shape to the tab) on the other of the lug 34 or the support 30. In this example, there is a tab 42a on each lateral side of the lug 34, and multiple recesses 42b on each lateral surface of the nape support portion 40 facing the lug 34. As will be appreciated, alternatively, the tab 42a may be on a lateral surface of the nape support portion 40, and the recess 42b may be on the lug 34. When the support 30 is pivoted from the stowed position, the tab 42a engages the recess 42b and provides a stopped position for the support 30. For example, the engagement of the tab 42a and the recess 42b resists further movement along the range of motion, which can also provide a tactile adjustment position when the tab 42a slides into the recess 42b. However, the tab 42a and the recess 42b are not deep enough to prevent the tab 42a from sliding out of the recess 42b when the occupant applies more force to further move the support member 30. As an example, to facilitate the tab 42a sliding in and out of the recess 42b, the tab 42a is a spherical dome (i.e., a portion of a sphere) and the recess 24b is a spherical dome recess. In addition, as also shown in the figure, by using a series of recesses 42b, such as a series of partially overlapping spherical dome recesses ( Figure 6 ), to provide a variety of adjustment positions. The overlap of the recesses 42b facilitates moving the tab 42a from one recess 42b to the next with minimal resistance, while still providing discrete tactile stop positions.
[0046] Although combinations of features are shown in the illustrated examples, not all of them need to be combined to achieve the benefits of the various embodiments of the present disclosure. In other words, a system designed according to an embodiment of the present disclosure will not necessarily include all of the features shown in any of the figures or all of the portions schematically shown in the figures. Furthermore, selected features of one example embodiment may be combined with selected features of other example embodiments.
[0047] The foregoing description is exemplary and non-restrictive in nature. Variations and modifications to the disclosed examples may become apparent to those skilled in the art without necessarily departing from the present disclosure. The scope of legal protection afforded to this disclosure may be determined only by studying the appended claims.
