Definitions

  • This invention relates to an air bag module for a vehicle, and more particularly, to an apparatus and method for installing an air bag module having a crash sensor disposed therein onto a vehicle.
  • Air bag modules conventionally include a crash sensor and are mounted on a vehicle in a manner to transmit crash information from the vehicle body to the crash sensor. Diagnostic circuits evaluate the crash information and discriminate between a fire and a no fire condition.
  • the airbag module is mounted on the vehicle such that the crash sensor will be subject to forces that indicate a crash condition.
  • the crash sensor usually comprises an accelerometer and the air bag module is rigidly coupled to a portion of the vehicle such that deceleration indicative of a crash condition is transmitted to the crash sensor.
  • the controller associated with the air bag module sends a signal to ignite an air bag deployment device.
  • Standard vehicle mounting technology requires an OEM to supply and properly mount three to four fasteners to join the mounting bracket and module to the vehicle to ensure adequate crash pulse transmission and effective crash discrimination.
  • a disadvantage of this method is that if any number or combination of fasteners is improperly fastened or missing, the crash indications may not be properly transmitted to the crash sensor. In that case, the performance of the air bag protection system may be compromised.
  • the standard mounting technology may also be problematic in terms of maintaining the efficiency of the vehicle assembly process if the air bag module must be mounted in a difficult-to-access location. If the mounting location is difficult to reach, for example, under the dashboard, an assembler may be forced to spend a relatively large amount of time to properly position and mount the air bag module.
  • An object of the present invention is to fulfill the need referred to above.
  • this objective is obtained by providing an air bag module for sensing a crash condition of a vehicle.
  • the vehicle has a mounting portion for mounting the air bag module thereto.
  • the mounting portion includes at least one slot and a fastener receiving structure coupled to the slot
  • the air bag module includes a housing assembly having first and second opposing ends. At least one mounting tab extends from the first end of the housing assembly.
  • a fastener is coupled to the second end of the housing.
  • the mounting tab is constructed and arranged such that when the mounting tab is inserted into the slot in the mounting portion of the vehicle and the fastener is inserted into and coupled with the fastener receiving structure, the mounting tab will deflect to be in a compressive state, whereby the fastener and mounting tab secure the air bag module to the mounting portion of the vehicle.
  • a method of mounting an air bag module to a vehicle to sense a vehicle crash condition is provided.
  • the vehicle has a mounting portion for mounting the air bag module thereto.
  • the mounting portion includes at least one slot and a fastener receiving structure spaced from the slot.
  • the method includes providing an air bag module comprising a housing assembly having first and second opposing ends. At least one mounting tab extends from the first end of the housing assembly. A stabilizing member protrudes from a surface of the housing assembly adjacent the first end thereof. A fastener is coupled to the second end of the housing assembly.
  • the method also includes inserting the mounting tab into the slot of the vehicle such that a portion of the mounting tab is disposed on a first side of the mounting portion and another portion of the mounting tab is disposed on a second side of the mounting portion opposite the first side, with the stabilizing member contacting the first side of the mounting portion.
  • the method includes inserting the fastener into and coupling with the fastener-receiving structure causing the mounting tab and the stabilizing member to be in a compressive state and secure the airbag module to the mounting portion.
  • FIG. 1 is a perspective view of an air bag module mounted to a mounting portion of a vehicle in accordance with the principles of the present invention
  • FIG. 2 is cross-sectional view of the air bag module mounted to a mounting portion of a vehicle in accordance with the principles of the present invention
  • FIG. 3 is an enlarged view of the circled portion in FIG. 2.
  • Air bag module 10 includes housing 12 which typically houses a crash sensor (not shown), for example an accelerometer, and diagnostic circuitry (not shown) to distinguish between a fire and a no fire condition.
  • a crash sensor for example an accelerometer
  • diagnostic circuitry to distinguish between a fire and a no fire condition.
  • the accelerometer and diagnostic circuitry may be disposed on a single printed circuit board housed in housing 12. The construction and placement of such accelerometer and diagnostic circuitry are known in the art and will not be discussed in detail here.
  • module 10 sends a signal to ignite an air bag triggering device (not shown) thereby deploying the airbag.
  • Bracket 15 preferably of sheet metal, is mounted to housing 12 at bottom surface 20. Together, the housing 12 and bracket 15 form a housing assembly. It can be appreciated that bracket 15 may be constructed to be an integral part of housing 12. Bracket 15 includes a pair of flexural mounting tabs 22 extending outwardly and in spaced relation with respect to each other from first end 14 of housing 12. As shown in FIG. 3, bracket 15 includes stabilizing member 24, which is preferably a portion of bracket 15 stamped to define a downwardly extending protrusion near first end 14 of housing 12, the function of which will become apparent below.
  • Second end 16 of housing 12 includes flange member 26, which carries threaded fastener 28.
  • Fastener 28 is preferably an M6 or M8 mounting fastener pre- installed with respect to flange member 26 and secured thereto via locking washer 30.
  • Air bag module 10 is configured to be mounted to mounting portion 32 of a vehicle.
  • mounting portion 32 is a portion of the vehicle's sheet metal and includes first and second slots 34 formed therein. First and second slots 34 are disposed in spaced relation to receive respective mounting tabs 22.
  • Mounting portion 32 also includes a fastener receiving structure in the form of nut 36 secured to underside 38 of mounting portion 32. Nut 36 is threaded to receive and be coupled to fastener 28. It is to be understood that any suitable fastener receiving structure may be used to receive fastener 28, including, but not limited to, a pierced conical hole provided in the sheet metal which could capture the fastener when fastener 28 is inserted therein.
  • Air bag module 10 is mounted with respect to vehicle mounting portion 32 as follows. Each mounting tab 22 is inserted into a respective slot 34 in mounting portion 32 such that portion 40 of each mounting tab is disposed on one side 44 of mounting portion 32 while another portion 42 of each mounting tab 22 is disposed on an opposite side, or underside 38, of mounting portion 32. At this stage of assembly air bag module 10 will be disposed in an unfastened, angle manner with respect to mounting portion 32. Next, pre-installed fastener 28 is inserted into nut 36 and tightened, which causes module 10 to rest on stabilizing member 24 and causes the mounting tabs to deflect. Both stabilizing member 24 and mounting tabs 22 are in a compressive state, simulating the mounting characteristics of fasteners.
  • Fastener 28 and the three additional "hard mount” locations provide the coupling to the mounting structure, in this case mounting portion 32, to promote adequate crash pulse transmission.
  • mounting structure in this case mounting portion 32
  • two mounting tabs 22 are shown, it can be appreciated that one generally centrally located mounting tab may be provided instead.
  • stabilizing member 24 may extend generally the width of module 10 or two stabilizing members may be provided near the edges of the module. Furthermore, although stabilizing member 24 provides an additional "hard mount” location, it can be appreciated that stabilizing member 24 may be omitted.
