Seatbelt Panel
Use the Seatbelt panel to create and route a seatbelt onto a dummy.
Location: Analysis page > Safety module
You can select a list of nodes and select components around which the seatbelts are to be routed/wrapped. Seatbelts can be created using 1D elements or a combination of 1D and 2D elements.
Panel Options
| Option | Action |
|---|---|
| node list | Select the nodes which
define the first endpoint, orientation nodes (used to guide the
initial belt position) and the last end point of the seatbelt.
Multiple nodes can be selected as orientation nodes to guide a smooth belt. |
| wrap around: (comps) | Select the component(s) that you want the seatbelt to be wrapped around. |
| toggle: 2D/1D or 1/D | Choose whether the seatbelt is treated as 1D (zero width, and so on) or a combination of 2D and 1D elements. |
| gap | Specify a gap between the belts and the dummy components to avoid any initial penetration. |
| element size | Specify the density of
the mesh for seatbelts. Note: Available when the dimension
toggle is set to 2D/1D.
|
| orient sensitivity | When in orient mode, this value can be modified to change the sensitivity of the interactive movement of the belt segments to mouse movement. |
| belt width | Specify the width (in
model units) of the belt. Note: Available when the dimension
toggle is set to 2D/1D.
|
| 1d length to start | Specify a distance the
1D elements must extend from the first endpoint of the seatbelt.
Note: Available when the dimension toggle is set to
2D/1D.
|
| 1d length to end | Specify a distance the
1D elements must extend from the last endpoint of the seatbelt.
Note: Available when the dimension toggle is set to
2D/1D.
|
| toggle: on release/real time |
Note: Available when the dimension toggle is set to
2D/1D.
|
| place 1D elems in | Select a collector to
place 1D elements that are created. Note: Available when the
dimension toggle is set to 2D/1D.
|
| place 2D elems in | Select a collector to
place 2D elements that are created. Note: Available when the
dimension toggle is set to 2D/1D.
|
| end type | Select whether the end
length of the seatbelt will be rigid links (default) or tria
surfaces. Note: Available when the dimension toggle is set to
2D/1D.
|
| mesh type | Select whether the
mesh of the seatbelt will be quads only (default) or R-trias.
Note: Available when the dimension toggle is set to
2D/1D.

Command Buttons
| Button | Action |
|---|---|
| orient | After you select the
desired end list and the wrap-around entities (components,
elements, or ellipsoids), click orient or
accept. Orient draws a full segment belt representation, which previews the orientation of the final belt. The two red end segments are linear and connect the end points selected to the previous intersection points on the dummy. The middle line segments follow the contour of the dummy and connect the two end segments. You can select each of the line segments and interactively orient them to a specific location. Once the final position is achieved, release the mouse to create a mesh that follows the specified path. The Update subpanel enables you to interactively change/update the element density and biasing. |
| accept | After you select the
desired end list and the wrap-around entities (components,
elements, or ellipsoids), click orient or
accept. Accept eliminates the belt segment preview and directly creates a mesh on the belt. You can then interactively change or update the element density and so on. |
| reject | Undo the most recent seatbelt orient/mesh operation. |
| return | Exit the panel. |
