Abstract

A display for viewing by a passenger from a seat on a vehicle when the display is mounted to structure in front of the passenger when the passenger is seated in the seat. The structure has a recess and a portion surrounding the recess. The display includes an electronic visual display panel for receiving a display signal and displaying information in correspondence therewith to the passenger on the electronic visual display panel. The display further includes a housing in which the electronic visual display panel is mounted or inserted, with the housing including a periphery. At least one fastener is provided including a structural fuse. The structural fuse deforms and/or fractures under force generated by a passenger's head striking the visual display panel in an accident. Due to crumple of the fuse, movement of the housing is permitted, with the display panel inserted therein, relative to the recess.

First claim

The invention claimed is:

1. A display for viewing by a passenger from a seat on a vehicle when the display is mounted to structure in front of the passenger when the passenger is seated in the seat, the structure having a recess and a portion surrounding the recess, the display comprising:
an electronic visual display panel for receiving a display signal and displaying information in correspondence therewith to the passenger on the electronic visual display panel;
a housing in which the electronic visual display panel is inserted, the housing having a periphery;
at least one fastener including a first part inserted through one of the periphery of the housing and the portion of the structure surrounding the recess and fastening to the other of the periphery of the housing and the portion of the structure surrounding the recess, when the housing with the electronic visual display panel inserted therein is received in the recess, the fastener having a second part connected to the first part and pressing said one of the periphery of the housing and the portion of the structure surrounding the recess and limiting movement of the housing with the electronic visual display panel relative to the recess, the fastener including a structural fuse comprising a reduced thickness portion of the fastener that deforms under force generated by a passenger's head striking the electronic visual display panel in an accident and due to elongation of the reduced thickness portion, permits movement of the housing, with the electronic visual display panel inserted therein, relative to the recess.

2. The display of claim 1 , wherein the reduced thickness portion of the fastener is formed in said first part of the fastener.

3. The display of claim 2 , wherein said first part of the fastener comprises a threaded shaft and the reduced thickness portion is formed symmetrically around a central axis of the threaded shaft of the fastener.

4. The display of claim 1 , wherein there is a plurality of fasteners.

5. The display of claim 1 , wherein the periphery includes a portion forming an upper edge of the housing and another portion forming the lower edge of the housing, and the first part of the fastener is inserted through one of the upper edge of the housing and the portion of the structure surrounding the recess and fastening to the other of the upper edge of the housing and the portion of the structure surrounding the recess.

6. A display for viewing by a passenger from a seat on a vehicle when the display is mounted to structure in front of the passenger when the passenger is seated in the seat, the structure having a recess and a portion surrounding the recess, the display comprising:
an electronic visual display panel for receiving a display signal and displaying information in correspondence therewith to the passenger on the electronic visual display panel;
a housing in which the electronic visual display panel is inserted, the housing having a periphery;
at least one fastener including a first part inserted through one of the periphery of the housing and the portion of the structure surrounding the recess and fastening to the other of the periphery of the housing and the portion of the structure surrounding the recess, when the housing with the electronic visual display panel inserted therein is received in the recess, the fastener having a second part connected to the first part and pressing said one of the periphery of the housing and the portion of the structure surrounding the recess and limiting movement of the housing with the electronic visual display panel relative to the recess, the fastener including a structural fuse that deforms under force generated by a passenger's head striking the electronic visual display panel in an accident and due to crumple of the fuse, permits movement of the housing, with the electronic visual display panel inserted therein, relative to the recess, wherein the fastener comprises a washer disposed around the first part of the fastener between the second part of the fastener and said one of the periphery of the housing and the portion of the structure surrounding the recess, the washer including an area of reduced yield resistance.

7. The display of claim 6 , further comprising a spacer disposed around the first part of the fastener between the washer and said one of the periphery of the housing and the portion of the structure surrounding the recess, the spacer including a larger diameter portion having a rim and the washer including a peripheral edge, in which the rim of the larger diameter portion abuts the peripheral edge of the washer.

8. A display for viewing by a passenger from a seat on a vehicle when the display is mounted to structure in front of the passenger when the passenger is seated in the seat, the structure having a recess and a portion surrounding the recess, the display comprising:
an electronic visual display panel for receiving a display signal and displaying information in correspondence therewith to the passenger on the electronic visual display panel;
a housing in which the electronic visual display panel is inserted, the housing having a periphery;
at least one fastener including a first part inserted through one of the periphery of the housing and the portion of the structure surrounding the recess and fastening to the other of the periphery of the housing and the portion of the structure surrounding the recess, when the housing with the electronic visual display panel inserted therein is received in the recess, the fastener having a second part connected to the first part and pressing said one of the periphery of the housing and the portion of the structure surrounding the recess and limiting movement of the housing with the electronic visual display panel relative to the recess, the fastener including a structural that deforms under force generated by a passenger's head striking the electronic visual display panel in an accident and due to crumple of the fuse, permits movement of the housing, with the electronic visual display panel inserted therein, relative to the recess,
wherein the periphery includes a portion forming an upper edge of the housing and another portion forming the lower edge of the housing, and the first part of the fastener is inserted through one of the upper edge of the housing and the portion of the structure surrounding the recess and fastening to the other of the upper edge of the housing and the portion of the structure surrounding the recess, wherein a fastener devoid of a structural fuse is inserted through one of the lower edge of the housing and the portion of the structure surrounding the recess and fastening to the other of the lower edge of the housing and the portion of the structure surrounding the recess.

9. A display for viewing by a passenger from a seat on a vehicle when the display is mounted to structure in front of the passenger when the passenger is seated in the seat, the structure having a surface opposing the passenger with a recess therein and a surface facing away from the passenger, the display comprising:
an electronic visual display panel for receiving a display signal and displaying information in correspondence therewith to the passenger on the electronic visual display panel;
a housing in which the electronic visual display panel is inserted, the housing having a periphery and including at least one aperture in the periphery, the aperture having a surrounding portion;
at least one fastener having a first part inserted through the aperture and into the surface facing away from the passenger when the housing with the electronic visual display panel inserted therein is received in the recess of the structure, the fastener having a second part connecte
