Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




The present invention relates generally to grab handles for vehicles and, more specifically, to a grab handle assembly for an interior of a motor vehicle.




2. Description of the Related Art




It is known to provide a headliner for an interior of a motor vehicle. The headliner is typically made as a single piece and is mounted to an interior side of a roof of a vehicle body of the motor vehicle. An example of such a headliner is disclosed in U.S. Pat. No. 5,845,458 to Patel. In this patent, the headliner includes a relatively stiff molded backing sheet and a relatively deformable foam panel adhesively secured to the undersurface of the backing sheet. Marginal edge areas of the foam panel in contact with hard side rails on the roof are provided with resilient deformable foam inserts that prevent the hard side rails from interfering with the energy absorption action of the foam panel.




It is also known to provide a handle for an interior side of a door of the motor vehicle. The handle includes a metal insert of a sufficient strength to sustain the loads that can be applied when closing the door. The handle also includes a molded body disposed over the metal insert.




It is desirable to provide a roof/pillar grab handle for an interior of a motor vehicle that has energy absorbing capacity if impacted by an occupant of the motor vehicle. It is further desirable to provide a grab handle that offers head impact energy absorption. Therefore, there is a need in the art to provide a grab handle assembly for a motor vehicle that meets these desires.




SUMMARY OF THE INVENTION




Accordingly, the present invention is a grab handle assembly for an interior of a motor vehicle. The grab handle assembly includes a headliner disposed in the interior of the motor vehicle for mounting to a vehicle body of the motor vehicle. The headliner has a recess. The grab handle assembly also includes a grab handle disposed in the recess and spaced from the vehicle body to absorb energy when impacted by an occupant in the interior of the motor vehicle.




One advantage of the present invention is that a grab handle assembly is provided for a motor vehicle that offers head impact energy absorption. Yet another advantage of the present invention is that the grab handle assembly has energy absorbing capacity for meeting requirements of an upper interior head impact. Still another advantage of the present invention is that the grab handle assembly is used for interior headform impact energy absorption for a roof/pillar of the motor vehicle.




Other features and advantages of the present invention will be readily appreciated, as the same becomes better understood, after reading the subsequent description taken in conjunction with the accompanying drawings.

DESCRIPTION OF THE PREFERRED EMBODIMENT(S)




Referring to the drawings and in particular

FIGS. 1 through 3

, one embodiment of a grab handle assembly


10


, according to the present invention, is illustrated for an interior or occupant compartment of a motor vehicle (not shown). The motor vehicle includes a vehicle body


12


forming a roof and pillars to define the interior of the motor vehicle. The motor vehicle includes the grab handle assembly


10


mounted to the vehicle body


12


in a manner to be described. It should be appreciated that, except for the grab handle assembly


10


, the motor vehicle and vehicle body


12


are conventional and known in the art.




The grab handle assembly


10


includes a headliner


14


to cover an interior side of the roof and side rails of the vehicle body


12


. The headliner


14


extends laterally and longitudinally and is generally rectangular in shape. The headliner


14


is made of a relatively stiff molded backing sheet


16


and a relatively deformable foam panel


18


adhesively secured to the undersurface of the backing sheet


16


. The headliner


14


is formed as a single piece. The headliner


14


has at least one depression or recess


20


adjacent a roof side rail, pillar or roof of the vehicle body


12


. The recess


20


extends inwardly toward the vehicle body


12


and is generally rectangular in shape for a function to be described.




The grab handle assembly


10


also includes a grab handle, generally indicated at


22


, disposed in the recess


20


and connected to, preferably the roof side rail, of the vehicle body


12


by suitable means such as fasteners (not shown). The grab handle


22


includes an inner strap


24


extending longitudinally and being generally rectangular in shape. The inner strap


24


is made of a metal material and is responsible for the required grab handle stiffness and energy absorption capability. The inner strap


24


has a predetermined thickness such as three millimeters (3 mm) and is made of mild steel or other similar metal alloys to act as an energy-absorbent spring.




The grab handle


22


includes a fastener


26


such as a screw extending through an aperture


28


in each end of the strap


24


and an aperture


30


in the headliner


14


and aperture


32


in the vehicle body


12


. The fastener


26


secures each end of the inner strap


24


to the vehicle body


12


. It should be appreciated that any suitable means may be used to attach the inner strap


24


to the vehicle body


12


.




The grab handle


22


also includes an outer cover


34


disposed over a majority of a length of the inner strap


24


. The outer cover


34


is generally tubular in shape and extends longitudinally. The outer cover


34


is made of a plastic material. It should be appreciated that the inner strap


24


extends through the outer cover


34


and that a user (not shown) grasps the outer cover


34


to grab onto the grab handle


22


.




The grab handle


22


further includes an end cap


36


to cover each end of the grab handle


22


. The end cap


36


is generally rectangular in shape. The end cap


36


extends longitudinally and has a cavity


38


in one longitudinal end to receive one end of the inner strap


24


and outer cover


34


. The end caps are made of a plastic material. It should be appreciated that the end caps


36


are attached by suitable means such as the fasteners


26


extending therethrough to the vehicle body


12


.




Optionally, the grab handle


22


may include a spacer (not shown) disposed between the inner strap


24


and the headliner


14


. The spacer is a generally rectangular plate made of a plastic material. The spacer is disposed between the inner strap


24


and backing sheet


16


to further offset the grab handle


22


from the vehicle body


12


.




In operation of the grab handle assembly


10


, the grab handle


22


is at an offset from the vehicle body


12


to which it is attached by being disposed in the recess


20


of the headliner


14


and spaced from the vehicle body


12


. Under normal vehicle operating conditions, the user may grasp the grab handle


22


. Since the grab handle


22


is offset, the grab handle


22


may prevent immediate contact with a stiffer portion of the vehicle body


12


such as the roof side rail or pillar flange during a vehicle collision. If the grab handle


22


is impacted, the inner strap


24


deforms to act as an energy-absorbent spring.




The present invention has been described in an illustrative manner. It is to be understood that the terminology, which has been used, is intended to be in the nature of words of description rather than of limitation.




Many modifications and variations of the present invention are possible in light of the above teachings. Therefore, within the scope of the appended claims, the present invention may be practiced other than as specifically described.
