DESCRIPTION OF PREFERRED EMBODIMENTS
Referring now to FIG. 1, which is an illustration of an automotive glove box assembly 10 in accordance with the present invention. The glove box assembly 10, includes an instrument panel substrate 12 to which a door panel 14 is rotatably mounted. A concern with modern glove box assemblies 10 arises from the desire for simply operated and aesthetically pleasing controls while preventing accidental or undesirable activation such as knee impact activation which occurs when a passenger's knee activates a latch holding the door panel 14 closed.
The present invention addresses these concerns through the use of a push button assembly 16 as detailed in FIG. 2. The push button assembly includes a push button element 18 with a button activation surface 20 having a button height 22 and a button width 24. A rigid button housing 26 houses the push button element 18 and forms a rigid perimeter 28 around the button activation surface 20. The rigid perimeter 28 in combination with the button height 24 are configured to prevent knee intrusion activation such as illustrated in FIG. 3. The push button element 18 may be activated by pressing inward within the rigid button housing 26, which thereby facilitates a latch element 30 to move from a door engagement position 32 to a door release position 34. The latch element 30 is preferably biased toward the door engagement position 32. Although button height 22 and button activation depth 36 (see FIG. 4) may be designed to solely remove knee intrusion activation, the present invention contemplates further improvements to reduce this undesirable result.
In one embodiment, the present invention contemplates the push button assembly 16 mounted within an outer display surface 38 of the instrument panel substrate 12 positioned directly above the door panel 14. The push button assembly 16 is preferably mounted within a recessed mount surface 40 having a recessed surface height 42 and a recess surface depth 44. The recessed surface height 42 and recessed surface depth 44 are configured to prevent knee intrusion activation. This is accomplished by minimizing the recessed surface height 42 and depth 44 until an acceptable range of knees 46 fail to generate activation. Although the recessed surface depth 44 may be held constant, in one embodiment it is contemplated that the recessed surface depth 44 progressively increases along the recessed surface height 42. This increase in depth 44 helps prevent intrusion activation.
Finally, it is contemplated that the door panel 14 may be formed with a tibia engaging surface 48 configured that such during impact a passengers tibia 50 contacts such a surface and the knee 46 is thereby directed away from the push button assembly 16 and the recessed mount surface 40. This further helps in insuring that during impact, a passenger's knee will fail to activate the push button assembly 16.
While the invention has been described in connection with one or more embodiments, it is to be understood that the specific mechanisms and techniques which have been described are merely illustrative of the principles of the invention, numerous modifications may be made to the methods and apparatus described without departing from the spirit and scope of the invention as defined by the appended claims.
