Insafe seat belt guide

Pregnant women should wear seatbelts in a way that the seatbelt does not cross and press the uterus.

INSAFE SEATBELT GUIDE redirects the lap belt away from the belly of pregnant woman to the hips and groin of the expectant mother, therefore, the force with which she can be ejected during an accident is not directly exerted to the belly, which guarantees greater safety for the developing foetus.

Before 3-point type seatbelt was invented, people wore 2-point type seatbelts where the seatbelt pressured people’s stomach. For this reason, people thought that The Road Traffic Law stipulates that pregnant women should be exempt from wearing seatbelts. However, after 3-point type seatbelts are invented, it is a mandatory that pregnant women also wears seatbelts.

To prevent seatbelt from crossing and pressuring pregnant women’s uterus, Insafe Seat Belt Guide was invented.
 No pressure on pregnant women’s stomach!
 Easy to wear

Before: DANGER! Strong force against pregnant women’s stomach!
After: In Safe breaks the strong energy that pressured the stomach.
