Display screen assembly
An assembly includes a display screen, a bracket for receiving and holding the display screen, a deformable mounting feature and a frangible mounting feature. The deformable mounting feature is adapted to absorb initial energy in the event of an impact to the display screen. The frangible mounting feature is adapted to further dissipate energy to the extent that the impact energy exceeds the ability of the deformable mounting feature to absorb it.
1. An assembly, comprising:
a support substrate;
a display screen;
a bracket receiving and holding said display screen wherein said bracket includes at least one display screen mounting point, a body having a first end, a second end and an intermediate section between said first end and said second end, a first mounting tab and a second mounting tab projecting from said intermediate section and wherein said intermediate section includes a first segment, a second segment, a third segment, a fourth segment and a fifth segment, a first bend connecting said first segment to said second segment, a second bend connecting said second segment to said third segment, a third bend connecting said third segment to said fourth segment, and a fourth bend connecting said fourth segment to said fifth segment;
a deformable mounting feature to absorb energy in event of an impact to said display screen, said deformable mounting feature including a first compression joint and a second compression joint joining said bracket and said support substrate wherein said first compression joint is provided at said first mounting tab and said second compression joint is provided at said second mounting tab; and
a frangible mounting feature, independent from said deformable mounting feature, to further dissipate energy from said impact, said frangible mounting feature including a first breakaway joint and a second breakaway joint wherein said first breakaway joint is provided at said first end and said second breakaway joint is provided at said second end and wherein said first compression joint and said second compression joint are inboard said first breakaway joint and said second breakaway joint.
2. The assembly of claim 1 , wherein said first segment is connected to said first end by a fifth bend and said fifth segment is connected to said second end by a sixth bend.
3. The assembly of claim 2 , wherein a first of said at least one display screen mounting point is provided at said first end, a second of said at least one display screen mounting point is provided at said second end and a third of said at least one display screen mounting point is provided at said third segment of said bracket.
4. The assembly of claim 3 , wherein said first mounting tab depends from said second segment and said second mounting tab depends from said fourth segment.
5. The assembly of claim 4 , further including a first fastener at said first compression joint, a second fastener at said second compression joint, a first frangible fastener at said first breakaway joint and a second frangible fastener at said second breakaway joint.
6. The assembly of claim 5 , further including a first rubber grommet at said first compression joint and a second rubber grommet at said second compression joint.
7. The assembly of claim 6 , wherein said first fastener includes a first bolt and a first cap washer, said first mounting tab, said first rubber grommet and a support substrate being sandwiched between said first bolt and said first cap washer.
8. The assembly of claim 7 , wherein said first rubber grommet includes a first receiver receiving said support substrate.
9. The assembly of claim 8 , wherein said first receiver is provided in said first rubber grommet toward a bracket end of said first rubber grommet.
10. The assembly of claim 9 , wherein said first cap washer includes a first channel receiving a cap washer end of said first rubber grommet.
