Display screen assembly

Abstract

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.

DETAILED DESCRIPTION

(7) Reference is now made to FIGS. 1 and 2 showing the new and improved assembly 10. That assembly 10 includes a display screen 12, a bracket 14, adapted or configured to receive and hold the display screen, a deformable mounting feature, generally designated by reference numeral 16, and a frangible mounting feature, generally designated by reference numeral 18. The deformable mounting feature 16 is adapted to initially absorb energy in the event of an impact to the display screen such as might occur during an accident of a motor vehicle equipped with the assembly. The frangible mounting feature 18 is adapted or configured to further dissipate injury from that impact should the impact energy exceed that which may be absorbed by the deformable mounting feature 16.

(8) Reference is now made to FIG. 2 illustrating the bracket 14 in detail. As illustrated, the bracket 14 includes a body 20 having a first end 22, a second end 24, and an intermediate section 26 extending between the first end and the second end. The bracket 14 further includes a first mounting tab 28 and a second mounting tab 30 projecting from the intermediate section 26.

(9) More specifically, the intermediate section 26 includes a first segment 32, a second segment 34, a third segment 36, a fourth segment 38 and a fifth segment 40. A first bend 42 connects the first segment 32 to the second segment 34. A second bend 44 connects the second segment 34 to the third segment 36. A third bend 46 connects the third segment 36 to the fourth segment 38 (note segment 38 includes a kink 39). A fourth bend 48 connects the fourth segment 38 to the fifth segment 40. A fifth bend 50 connects the first segment 32 to the first end 22. A sixth bend 52 connects the fifth segment 40 to the second end 24. The first mounting tab 28 in the illustrated embodiment depends from the second segment 34. The second mounting tab 30 depends from the fourth segment 38.

(10) As illustrated in FIGS. 1, 3 and 4, the deformable mounting feature 16 of the illustrated embodiment includes at least one compression joint and, more particularly, a first compression joint, generally designated by reference numeral 54, and a second compression joint, generally designated by reference numeral 56. The frangible mounting feature 18 of the illustrated embodiment includes a first breakaway joint 58 and a second breakaway joint 60. In the illustrated embodiment, the first compression joint 54 and the second compression joint 56 are provided inboard of the first breakaway joint 58 and the second breakaway joint 60. More particularly, the first breakaway joint 58 is provided at the first end 22 of the bracket 14 while the second breakaway joint 60 is provided at the second end 24 of that bracket. The first compression joint 54 is provided at the first mounting tab 28 while the second compression joint 56 is provided at the second mounting tab 30.

(11) In the illustrated embodiment at least one display screen mounting point is provided on the bracket 14. More particularly, in the illustrated embodiment a display screen mounting point 62 is provided at the first end 22, the second end 24 and the third segment 36 of the bracket 14.

(12) More specifically, a first fastener 64 is provided at the first compression joint 54. A second fastener 66 is provided at the second compression joint 56. A first frangible fastener 68 is provided at the first breakaway joint 58 and a second frangible fastener 70 is provided at the second breakaway joint 60. Each of the frangible fasteners 68, 70 is engineered to break when subjected to a particular impact force wherein that particular impact force exceeds the impact force capable of being dissipated by the compression joints 54, 56 of the deformable mounting feature 16.

(13) Still further, the assembly 10 includes a first rubber grommet 72 at the first compression joint 54 and a second rubber grommet 74 at the second compression joint 56. The first fastener 64 also includes a first bolt 76 and a first operating cap washer 78. The first mounting tab 28, the first rubber grommet 72 and a part of the support substrate 80 to which the assembly 10 is mounted, are sandwiched between the first bolt 76 and the first cooperating cap washer 78. Toward this end, the first rubber grommet 72 includes a first receiver (hidden from view in FIG. 3) that receives and holds the support substrate 80. That first receiver is provided in the first rubber grommet 72 toward a bracket end of the first rubber grommet. The first cap washer 78 includes a first channel (also hidden from view) for receiving the cap washer end of the first rubber grommet 72.

(14) Similarly, as illustrated in FIG. 4, the second fastener 66 includes a second bolt 86 and a second cap washer 88. The second mounting tab 30, the second rubber grommet 74 and the support substrate 80 are sandwiched between the second bolt 86 and the second cap washer 88.

(15) That second rubber grommet 74 includes a second receiver 90 to receive and hold the support substrate 80. That second receiver 90 is provided in the second rubber grommet 74 toward a bracket end of the second rubber grommet. The second cap washer 88 includes a second channel 92 that receives a cap washer end of the second rubber grommet 74. The first receiver and first channel that are hidden from view in FIG. 3 correspond in structure to the second receiver 90 and second channel 92 illustrated in FIG. 4.

(16) As should be appreciated, the first and second rubber grommets 72, 74 of the first and second compression joints 54, 56 provide a damping action that dissipates any impact force initially applied to the display screen 12 thereby absorbing impact energy. The depth of the first and second channels 92 of the respective first and second cap washers 78, 88 may be engineered to provide tuning for compression rate and dissipation of impact force. Significantly, as best illustrated in FIG. 4, the support substrate 80 is received in the second receiver 90 in the second rubber grommet 74 that is closer to the second mounting tab 30 of the bracket 14 than the channel end of the second cap washer 88. Here it should be appreciated that the short side of the second rubber grommet 74 between the bracket 14 and the fixed support substrate 80 compresses minimally when the display screen 12 is pulled rearward while the long side 98 of the second rubber grommet 74 compresses substantially more when the display screen 12 is impacted by a motor vehicle occupant during a collision event. Here it should be appreciated that the first compression joint 54 including the first rubber grommet 72 has the same configuration as the second compression joint 56 and the second rubber grommet 74 in order to function in the same manner.

(17) The foregoing has been presented for purposes of illustration and description. It is not intended to be exhaustive or to limit the embodiments to the precise form disclosed. Obvious modifications and variations are possible in light of the above teachings. All such modifications and variations are within the scope of the appended claims when interpreted in accordance with the breadth to which they are fairly, legally and equitably entitled.
