Abstract

A vehicle body structure includes a first panel, a second panel, a pulse detection sensor and a gap reduction member. The first panel has a first main section and a sensor installation location that is spaced apart from the first main section. The second panel has a second main section that is spaced apart from the first main section of the first panel and defines a gap therebetween. The pulse detection sensor is attached to the first panel at the sensor installation location. The gap reduction member is installed to the first main section of the first panel. The gap reduction member extends from the first main section toward the second main section within the gap.

a pulse detection sensor attached to the first panel at the sensor installation location; and

a gap reduction member installed to the first main section of the first panel, the gap reduction member extending from the first main section toward the second main section within the gap, with the gap reduction member being spaced apart from each of the first pillar structure and the second pillar structure.

2. The vehicle body structure according to claim 1, wherein

the gap between the second main section and the first main section of the first panel defines a first distance measured between the first main section and the second main section.

3. The vehicle body structure according to claim 2, wherein

the gap reduction member has a first end and a second end, the first end being fixed to the first main section, the second end being spaced apart from the second main section, the gap reduction member defining a first length measured from the first end to the second end, the first length being less than the first distance.

4. The vehicle body structure according to claim 2, wherein

the gap reduction member has a first end and a second end, the first end being fixed to the first main section, the second end being pressed against the second main section, the gap reduction member defining a first length measured from the first end to the second end, the first length being equal to the first distance.

5. The vehicle body structure according to claim 1, wherein

the gap reduction member attaches to the first main section via mechanical fasteners.

6. The vehicle body structure according to claim 1, wherein

the gap reduction member includes a dovetail section and the first main section defines a slot with the dovetail section being installed to the slot.

7. The vehicle body structure according to claim 1, wherein

the gap reduction member is fitted between the first main section and the second main section such that the gap reduction member contacts both the first main section and the second main section.

8. The vehicle body structure according to claim 7, wherein

the second panel, the first panel, the gap reduction member and the pulse detection sensor are configured and arranged such that in response to a predetermined level of force being applied to at least one of the first panel and the second panel, movement of the at least one of the first panel and the second panel toward the other of the first panel and the second panel causes the pulse detection sensor to detect the predetermined level of force.

9. The vehicle body structure according to claim 1, wherein

the gap reduction member has a first end installed to the first main section and a second end that is located adjacent to the second main section of the second panel in a non-contacting relationship relative to the second main section of the second panel.

10. The vehicle body structure according to claim 9, wherein

the second panel, the first panel, the gap reduction member and the pulse detection sensor are configured and arranged such that in response a predetermined level of contacting force being applied to the second panel, the predetermined level of force is transmitted through the gap reduction member to the first panel such that the predetermined level of force is detected by the pulse detection sensor.

11. The vehicle body structure according to claim 1, further comprising:

a controller connected to the pulse detection sensor at least partially defining a force contact response system.

12. The vehicle body structure according to claim 11, wherein

the force contact response system includes an airbag system having at least one airbag, a triggering device and the pulse detection sensor, the pulse detection sensor and the triggering device being configured such that in response to the pulse detection sensor detecting a predetermined level of force being applied to one of the first panel and the second panel, the triggering device causes the airbag to inflate.

13. The vehicle body structure according to claim 1, wherein

the gap reduction member is made of a material selected from a material consisting of one of the following:

an injection molded material and a light-weight rigid foam material.

14. The vehicle body structure according to claim 1, wherein

the first panel is an inner body panel and a second panel is an outer body panel that together define a side wall section of the vehicle.

15. The vehicle body structure according to claim 1, wherein

the first panel and the second panel being rigidly connected to one another at locations spaced apart from the gap reduction member.

16. A vehicle body structure comprising:

a floor of a passenger compartment;

a roof rail;

an inner panel having a plurality of first attachment locations along the roof rail and proximate the floor, a window receiving area, a first main section and a sensor installation location that is spaced apart from the first main section, the inner panel being attached to the floor, the first main section extending in a vertical direction beneath a central portion of the window receiving area;

an outer panel having a plurality of second attachment locations along the roof rail and proximate the floor that are rigidly coupled to corresponding locations of the plurality of first attachment locations of the inner panel and a second main section defining a wall section of a vehicle, with the second main section being spaced apart from the first main section of the inner panel defining a gap therebetween, the outer panel being attached to the roof rail;

a pulse detection sensor attached to the inner panel at the sensor installation location;

an airbag assembly installed within the vehicle and connected to the pulse detection sensor; and

a gap reduction member that is non-compressible installed to the first main section of the inner panel below the window receiving area and above the floor such that the gap reduction member is closer to the floor than to the window receiving area, the gap reduction member extending from the first main section toward the second main section within the gap, the gap reduction member being configured and located to define a force transmitting element such that in response to a predetermined level of force being applied to the outer panel proximate the gap reduction member, at least a portion of the predetermined level of force is transmitted from the outer panel through the gap reduction member to first main section of the inner panel such that the predetermined level of force is detected by the pulse detection sensor triggering deployment of the airbag assembly.
