Vehicle seat with stowable headrest

Abstract

An apparatus is for providing seating in a vehicle passenger compartment. A vehicle seat includes a headrest for forming at least a portion of a seating surface of the vehicle seat in a stowed position and a panel for forming the portion of the seating surface in a deployed position of the headrest. The stowed headrest may be positioned in a cavity formed in the seat. The panel may be connected to the headrest, and at least partially sandwiched between an inner surface of the cavity and the headrest in the stowed position.

DETAILED DESCRIPTION

(7) As shown in FIG. 1, a motor vehicle V has a passenger compartment or cabin C including a seat S having a headrest 10, which typically matches the seat in terms of the material and construction (e.g., a durable, smooth covering, such as leather, with a soft or spongy interior, typically made of foam or a like resilient material). In the deployed position, as shown, the headrest 10 typically projects vertically about the upper perimeter of the seat S. Thus, it provides a convenient and comfortable place for a passenger to rest their head while seated.

(8) The headrest 10 is mounted for moving between the deployed operative position (FIGS. 1 and 3) and the stowed position (FIGS. 2 and 4), while at all times remaining connected to the seat S. This can be achieved by providing one or more supports 12 that are pivotally mounted to the seat S, such as within a recess formed along an upper portion thereof, to allow for movement of the headrest along a generally arcuate path A. The pivot point P may be established by a fixed, transverse post 14 about which each support 12 may pivot, such as by connection to an intermediate portion between the ends (one of which may be recessed within the material of the headrest 10). To lend stability and ensure longevity over the operative life of the vehicle, two such supports may be provided, and the post 14 may be connected directly to the seat S or an intermediate part (not shown). The support(s) 12 may comprise slender, metal (stainless steel) rods, and may be generally L-shaped, the reasons for which orientation will become clearer upon reviewing the following description.

(9) The seat S is provided with a cavity 16 for receiving the headrest 10 in the stowed position, such that it forms a part or portion of the seating surface. As perhaps best shown FIG. 4, the arrangement may be such that the headrest 10 when stowed is flush with the forward face of the seat S, such as the portion for engaging a passenger's upper back or shoulders when seated. Consequently, the stowing of the headrest 10 does not impact the comfort of the seated passenger in any material way, yet provides a convenient place for storing the headrest when not needed or desired (and without the need for detaching it from the seat S).

(10) To cover the cavity 16 when the headrest 10 is deployed and form the otherwise missing portion of the seating surface, a movable panel 18 may be provided as an integral part of the seat S. The panel 18 may be connected to the seat S at one end portion, such as along an upper edge 16a of the cavity 16. The connection may be established along the entire perimeter of the seat surface surrounding the cavity 16 or a portion thereof, except for the part forming the connection to the support 12 for supporting the headrest 10 at the other end portion. The panel 18 may comprise a material that covers the cavity 16 when the headrest 10 is deployed, but then is recessed within the cavity between the headrest and an inner surface 16b (such as the rear most portion, which is a generally vertical wall) of the cavity when stowed, and thus sandwiched therebetween.

(11) Consequently, as can be understood with reference to FIG. 1, the panel 18, and the upper portion thereof in particular, is caused to move from a first (typically rearward) position closer to the inner surface 16b of the cavity 16 in the seat S, to a second (typically forward) position as a result of the movement of the support(s) 12 about the pivot point P, which is of course caused by the movement of the headrest 10 (which may be manual or automatic). In the erected position, the panel 18 thus covers the cavity 16 and provides a continuous seating surface that is aesthetically pleasing and also functional in the sense that it should not interfere with the comfort of the seated passenger (whose shoulders and upper back may still engage the surrounding surfaces of the seat S). Furthermore, the deployment of the panel 18 can be achieved by a passenger while seated by simply leaning forward and erecting the headrest 10.

(12) In one particular embodiment, the material is sufficiently flexible such that it can move from a relaxed, folded or flaccid form during stowage of the headrest 10 (FIG. 4) to a taut position for covering the cavity 16 in the deployed position. As can be appreciated, the taut state is fully maintained by the weight and position of the headrest 10 (which may be associated with a locking mechanism for holding it in place when deployed) by virtue of the connection to the upper end portion of the panel 18. Alternatively, the material may be of a dimension to cover the cavity 16 in the deployed position of the headrest 10 (perhaps in a semi-relaxed or partially taut state), and then assume the recessed position within cavity without stretching simply by adjusting the geometry of the arrangement. The connected end portion 12a of the support 12 may also comprise an oversized, rounded part to allow for any excess material of the panel 18 to be wound partially around it to remove any excess slack.

(13) The relative sizing in terms of width or thickness of the headrest 10 and the panel 18 may also be adjusted as necessary or desired. For instance, as indicated in FIG. 3, undersizing the headrest 10 (note dashed line profile) may allow for the panel 18 to be oversized a corresponding amount to occupy a greater portion of cavity 16 in the deployed position. The thickened panel 18 that results may thus be made more rigid and thus assume more pressure from a seated passenger, which may be desirable in some applications. In any case, a desirable approach is for the thickness of the headrest 10 plus the thickness of the panel 18 to be approximately equal to the depth of the cavity 16. The panel 18 may also be designed to fold and unfold in a preferential manner, such as by providing creases, fold lines, or the like.

(14) In summary, an improved stowable headrest 10 is provided that can be stowed in position for forming a part of the seating surface, and then deployed for the desired head support and resting function while remaining connected to the seat. A cavity 16 in the seat S receives the headrest 10 when stowed, thus avoiding the need for removal and separate storage. Yet, when deployed, a panel 18 covers the cavity 16, thus providing an aesthetically pleasing and comfortable solution for the passenger seating.

(15) The foregoing has been presented for purposes of illustration and description. It is not intended to be exhaustive or to limit the embodiments to the precise form disclosed. Obvious modifications and variations are possible in light of the above teachings. All such modifications and variations are within the scope of the appended claims when interpreted in accordance with the breadth to which they are fairly, legally and equitably entitled.
