Patent Application
20190375342
This document relates generally to the motor vehicle equipment field and, more particularly, to a new and improved display screen assembly wherein the display screen is secured by a mounting bracket with a deformable mounting feature to initially absorb energy in the event of an impact event and a frangible mounting feature to further dissipate that energy when that energy exceeds the ability of the deformable mounting feature to absorb energy.
As motor vehicles evolve, it is proposed to utilize display screens for displaying information at new positions not previously considered for this purpose. For example, a display screen may now be provided protruding from the center stack of the instrument panel. In other vehicles such as autonomous vehicles, display screens may be mounted in headrests or along the seat back, mounted to headliners or even to pillars such as the B and C pillars between rows of seating.
Many of these new display screen positions mean that the display screens could potentially be impacted by an occupant in the event of a sudden impact such as due to a collision. Accordingly, it is more important than ever to ensure that the display screen assembly has the necessary features to dissipate energy due to human impact and thereby improve safety.
This document relates to a new and improved assembly for a display screen incorporating both a deformable mounting feature to initially absorb energy in the event of an impact and a cooperating frangible mounting feature to further dissipate energy in the event the impact energy exceeds the capability of the deformable mounting feature to absorb the energy.
In accordance with the purposes and benefits as described herein, a new and improved assembly is provided. That assembly comprises a display screen, a bracket receiving and holding that display screen, a deformable mounting feature to absorb energy in the event of an impact to the display screen and a frangible mounting feature to further dissipate energy from the impact when that energy exceeds the capability of the deformable mounting feature to absorb that energy.
More specifically, the assembly may include at least one display screen mounting point on the bracket. Further, the deformable mounting feature may include at least one compression joint. In other embodiments, the deformable mounting feature may include a first compression joint and a second compression joint.
The frangible mounting feature may include a first breakaway joint and a second breakaway joint. In some of the many possible embodiments of the assembly, the first compression joint and the second compression joint are provided inboard of the first breakaway joint and the second breakaway joint.
The bracket may include a body having a first end, a second end and an intermediate section between the first end and the second end. Further, the bracket may include a first mounting tab and a second mounting tab projecting from the intermediate section.
The first compression joint may be provided at the first mounting tab. The second compression joint may be provided at the second mounting tab. The first breakaway joint may be provided at the first end of the bracket. The second breakaway joint may be provided at the second end of the bracket.
The intermediate section of the bracket may include a first segment, a second segment, a third segment, a fourth segment and a fifth segment. The intermediate section may further include a first bend connecting the first segment to the second segment, a second bend, connecting the second segment to the third segment, a third bend, connecting the third segment to the fourth segment and a fourth bend, connecting the fourth segment to the fifth segment. Still further, the first segment may be connected to the first end by a fifth bend. The fifth segment may be connected to the second end by a sixth bend.
In one or more of the many possible embodiments of the assembly, the display screen mounting point may include three attachment points provided, for example, at the first end, the second end and the third segment of the bracket. In addition, the first mounting tab may depend from the second segment. The second mounting tab may depend from the fourth segment.
The assembly may further include a first fastener at the first compression joint, a second fastener at the second compression joint, a first frangible fastener at the first breakaway joint and a second frangible fastener at the second breakaway joint.
Still further, the assembly may include a first rubber grommet at the first compression joint and a second rubber grommet at the second compression joint. In one or more of the many possible embodiments of the assembly, the first fastener may include a first bolt and a first cooperating cap washer. The first mounting tab, the first grommet and a support substrate maybe sandwiched between the first bolt and the first cooperating cap washer. Further, the first rubber grommet may include a first receiver receiving the support substrate. That first receiver may be provided in the first grommet toward a bracket end of the first grommet. In such an embodiment, the first cap washer may include a first channel receiving a cap washer end of the first grommet.
