BACKGROUND
1. Field of the Invention
The present invention relates access to the trunk of an automotive vehicle, and more specifically relates to access to the trunk from within the passenger compartment of the vehicle.
2. Description of Related Technology
A trunk of an automotive passenger vehicle is usually the vehicle's main cargo compartment. The trunk is located at the rear of the vehicle, and in sedan-type vehicles, the trunk is separated from the passenger compartment. To increase the flexibility of the trunk load space, the addition of folding rear seats increases the size of the trunk and so allows the occasional transportation of luggage that would have otherwise required a much larger vehicle. Beginning with the 2002 model year, a glow-in-the-dark trunk release was required inside the trunk of all U.S. vehicles with separate trunks. This was done in order to provide an escape for persons locked in the trunk.
Some cars currently include the ability to remotely open the trunk from the outside or from inside the passenger compartment. This may be achieved through a variety of options, for example through an electronic release switch for the trunk's latch, which may cause the trunk lid to raise or merely unlatch. These options typically require an electric power supply.
It is desirable to provide a mechanism for opening of the trunk from the passenger compartment of the vehicle, even if the vehicle ignition is turned off and no electric power supply is available.
SUMMARY OF THE INVENTION
The present invention provides a separating panel assembly with an opening through a portion of the separating panel and with a access chute adjacent to the opening on a side of the separating panel facing the trunk. The access chute is configured to guide a person's hand, which has been inserted into the opening from the passenger compartment, to a trunk release handle located adjacent to the access chute.
In one aspect of the invention, the opening is configured to be located behind a foldable armrest when the armrest is folded up.
According to another aspect of the invention, the opening may have a cover, the cover being movable for uncovering the opening. Such a cover may be hinged or flexible and inhibits air flow from the trunk into the passenger compartment. A flap made of elastomeric material resists permanent deformation.
According to a further aspect of the invention, the opening may be framed by a plastic bezel on a side facing the passenger compartment. The bezel provides a suitable fastening location for the cover.
According to yet another aspect of the invention, the chute may extend primarily in a horizontal, rearward direction, relative to the vehicle, from the opening. The chute may have a bottom wall primarily extending in a horizontal plane and two primarily vertical side walls located adjacent to the bottom and extending substantially parallel to each other. This arrangement guides an inserted hand toward the trunk release handle. A top wall may be added depending on spatial conditions inside the trunk. Accordingly, the chute inhibits contact between the hand and other devices located inside the trunk and that are laterally or vertically outside or beside the chute.
Therefore, the chute defines a channel with a bottom wall and a top wall, the chute being arranged in a position with the trunk release handle within a projected cross-section of the channel.
In another aspect of the invention, the separating panel itself may be foldable about a bottom hinge configured for folding the separating panel down into the passenger compartment.
Further, the separating panel may be laterally attached to a back rest of an adjacent seat and hingeable with the back rest into the passenger compartment.

DETAILED DESCRIPTION OF THE DRAWINGS
Referring to FIG. 1, a separating panel 10 is shown in a view as it presents itself when viewed rearward from within a vehicle passenger compartment. The separating panel 10 separates the passenger compartment from the vehicle's trunk, which is located behind the separating panel 10.
The separating panel 10 generally includes a substantially vertical portion 12 located between two back rests 22 and 24 of two back seats of the vehicle. The substantially vertical portion 12 may be connected to a substantially horizontal portion 14 and may be manufactured of stamped sheet metal or an alternative material, such as on of a variety of plastics, particularly reinforced plastics. The back rests may include various openings, for example head rest apertures 16 for accommodating adjustment rods of head rests associated with rear seats. The horizontal portion 14 may also have openings 18 and 20, such as openings to receive a back rest release or loudspeakers. Although the separating panel 10 is depicted as one piece in FIG. 1, it is contemplated that the separating panel 10 may be assembled from several separate parts and may be configured not to include the horizontal portion 14. The vertical portion 12 of the separating panel 10 forms a center back rest between the back rests 22 and 24 and is configured for accommodating a hingeably mounted armrest 28 (seen in FIGS. 3 and 4) between the back rests 22 and 24. The center back rest 26 is hidden behind the armrest 28 when the armrest 28 is folded upward so that it forms a generally planar continuous back rest surface with the back rests 22 and 14 arranged on both lateral sides of the center back rest 26. When the armrest 28 is folded down to support an arm, a bezel 30 is revealed that has a central opening 32. In the depicted embodiment, the central opening 32 has a rectangular shape with rounded corners. This shape is only one example out of many possibilities, and the central opening 32 may be round or oval or have any other shape suitable for insertion of a human hand.
The separating panel 10 may be hingeable forward about a bottom hinge 56 (shown in FIG. 3) to provide an opening with a large cross-section between the passenger compartment and the vehicle's trunk for transporting large items. Also, the separating panel 10 may have a vertical off-center split between back rest 22 and center section 26 or between back rest 24 and center section 26, or both, so that two or more separately hingeable portions may be formed. This allows folding an individual back rest 22 or 24, or one of the back rests 22 and 24 including the center back rest 26, forward into the passenger compartment to provide an enlarged opening between the passenger compartment and the vehicle's trunk while retaining the other one of the back rests 22 and 24 upright for seating a passenger.
FIG. 2 shows the bezel 30 and the central opening 32 in greater detail. Along the top of central opening 32, a fastening strip 34 is formed on the bezel 30. The fastening strip 34 is indicated by a broken line because it is concealed by a flap 36 that substantially covers the central opening 32. The flap 36 is made of a flexible polymer material and affixed to the fastening strip 34 via three snap connectors 38. While the drawing shows three snap connectors 38, any number of two or more would be suitable as well. Also, for attaching the flap 36, plastic rivets, or other suitable attachment techniques, including the use of adhesive or a melting process, such as ultrasonic welding, can be used for forming spots or lines connecting the flap 36 with the fastening strip 34. Furthermore, the flap 36 may be rigid and hingeably mounted. In the shown embodiment, the flap 36 is sufficiently flexible to bend into or out of the central opening 32, thereby allowing access to an access chute 40 leading rearward into the trunk of the vehicle. The flap 36 may be made of elastomeric material for avoiding permanent deformation upon use. The material may also be opaque or transparent. By providing the flap 36 over the opening 32, the flap 36 minimizes air flow from the trunk to the passenger compartment, while at the same time allowing easy access to the central opening 32 and the access chute 40. The access chute 40 may be manufactured of thermoplastic material and may also be integral or unitarily formed with the bezel 30 and secured to the separating panel 10. The access chute 40 may move with the separating panel when the separating panel 10 is folded down about hinge 56. Alternatively, the access chute 40 may be detachable from the separating panel 10.
Behind the flap 36, near the rearward end of the access chute 40, a trunk release handle 42 is located. The trunk release handle 42 is positioned adjacent to the access chute 40 such that it is within reach of a hand inserted into the central opening 32 by bending the flap 36 inward or outward. In the figure, the release handle 42 is actuated by pulling the handle 42 to the left.
FIG. 3 shows a side view of the separating panel separating panel 10 and the access chute 40 from the right side of the vehicle so that the front of the vehicle is on the right side of the drawing and the rear of the vehicle is on the left side of the drawing. The access chute 40 extends from the rear side of the separating panel 10 in a generally horizontal direction and defines a channel having a substantially horizontal bottom 44 flanked by two adjacent side walls 46, of which only one is visible in this view. A top wall 48 connects the top edges of the side walls 46. In the shown embodiment, the top wall 48 does not extend in a straight horizontal plane over its entire length, but rather is stepped at 50 with a lowered height toward the rear of the vehicle. The step 50 lowers the height of the access chute 40 to guide the inserted hand downward underneath a frame duct 52 that is arranged crosswise between the passenger compartment and the trunk and provides rigidity to the vehicle frame and allows routing of electrical lines or conduits. While the bottom wall 44 extends rearward partly underneath the frame duct 52, the top wall 48 is shorter than the bottom wall 44 and ends before reaching the frame duct 52. In alternative embodiments, the top wall 46 of the access chute 42 may extend as far as the bottom wall 44, may be straight, have a slope or a curvature, or may be omitted entirely, depending on spatial conditions inside the trunk and the location of the opening 32 in the separating panel 10.
A push-pull cable 54, with a core wire and a tubular cover, is guided forward with respect to the vehicle from a trunk lock latch (not shown) along a side wall of the trunk, along the underside of the horizontal portion 14, and to an anchor bracket 58 located within a rearward projection of the cross-section of the access chute 40. The trunk release handle 42 is fixedly connected to the core of the push-pull cable 54 and positioned mostly underneath the frame duct 52, preferably near the front side of the frame duct 52. Pulling the trunk release handle 42 disengages the trunk lock latch, thereby opening or at least unlocking the trunk lid. The trunk release handle 42 may have a dual function as an emergency trunk release that is accessible from inside the trunk to enable persons locked in a trunk to escape. But it is also within the scope of the present invention that a separate emergency trunk release may be provided in addition to the trunk release handle 42.
As illustrated in FIG. 3, the trunk release handle 42 is preferably located within a rearward projection of cross-section A of the channel, which is formed by the access chute 40. It is optional to place the trunk release handle inside the access chute 40. Even if the trunk release handle 42 is located beyond the rearward end of the access chute 40, extending a hand into the access chute 40 preferably leads easily to a contact with the trunk release handle 42 due to the geometrical arrangement of the access chute 40 and the trunk release handle's position adjacent to the access chute 40. In the shown embodiment, the position of the trunk release handle 42, indicated with an arrow, is at a height closer to the bottom wall 44 than to the top wall 48 of the access chute 40. A hand gliding rearward along the straight bottom 44 is guided directly toward the trunk release handle 42. Such a location makes accessing the trunk release handle through the opening easy, even if the trunk release handle is not directly visible to the person inserting their hand into the central opening 32.
FIGS. 4 and 5 show different perspective views of the access chute 40. FIG. 4 shows the access chute 40 from the passenger side of the vehicle, looking slightly rearward and downward. FIG. 5 shows a similar perspective from the driver side of the vehicle, but from a closer viewing position. As evident from FIG. 4, and particularly FIG. 5, the trunk release handle 42 is located beneath the frame duct 52 and protrudes slightly beyond the front edge of the frame duct 52 to form a horizontal loop at a height between the top wall 48 and the bottom wall 44 of the access chute 40, within the projection of the cross-section A of the access chute 40.
Both FIGS. 3 and 4 show portions of the armrest 28 in a folded-up position that covers the central opening 32. For access to the central opening 32, the armrest 28 can be folded down, thereby revealing the center back rest 26 of the separating panel 10.
While the figures depict the trunk release handle 42 as a loop, other shapes are within the scope of the present invention, such as T handles or pivoting arrangements. Also, mechanical linkages other than push-pull cables can be used to transfer an actuation of the trunk release handle to the trunk lock. The push-pull cable 54 provides the benefit of simple flexible installation along the side of the trunk where it does not interfere with the storage area of the trunk.
The invention may be embodied in other forms without departing from the spirit or novel characteristics thereof. The embodiments disclosed in this application are to be considered in all respects as illustrative and not limiting. Furthermore, details described in connection with one embodiment may be adapted to be implemented in a different embodiment. The scope of the invention is indicated by the appended claims rather than by the foregoing description; and all changes which come within the meaning and range of equivalency of the claims are intended to be embraced therein.
