Some damn fool here suggested using custard to restrain
passengers in the event of a crash.
A better idea would be to make seatbelts out of silly putty, or
at least out of a flexible tube filled with silly putty.
At rest, the silly putty will gradually contract, snuggling up
the belt. In
the event of an abrupt deceleration (crash), the
silly putty core of the belt will resist rapid extension,
restraining the passengers.
not as silly but this could work

It's that dilatant lifestyle you lead, [Max]. |
|
| |
I see what you did there.
|
|
| |
dilatant = material is one in which viscosity increases with the rate of shear strain.
|
|
| |
dilettante = a person who is or seems to be interested in a subject, but whose understanding of it is not very deep. |

It must be a substance exactly not unlike but slightly dissimilar to Silly Putty. If you pull the putty apart slightly, then give it a rapid tug, it will snap clean, a property not typically sought in seat belts. |
|
| |
I continue to be interested in what sort of images might be transferred onto (and into) the Silly Putty seatbelts upon impact, and how might this be made into a unique selling feature. |

Regarding the technology in the link, seatbelt
pretensioners are all very well and good, but who
wants a pretentious seatbelt? |
|
| |
What would be their particular affect, [Max]? |
|

In response to tatterdemalion's comment, it could be designed so that the main structure of the seatbelt is a mesh of strong fibers woven on a diagonal bias so that the space between the fibers is large when the tension is low, but becomes small when tugged. If the putty were incorporated to fill these spaces, then the impact would serve to squeeze the putty out of the spaces, thus loading it in compression rather than tension. The issue of snapping putty is thus solved. |
