Short answer is Yes. As far as I know, most cars have the 3 point seat belt.
Padded steering wheel. collapsible steering column, more padding on the dash, and seat belt shoulder harness.
It should have the shoulder and seat belt.
A head-on collision.
Lap and shoulder belt combinations in your car are called safety belts
You can use the car seat as a "booster" by using the shoulder harness straps on the upper sides to hold your Car Seat Belt over your child - the seat "boosts" them up so that the seat belt crosses and restrains them at a safe level. This may be confused with other "backless-booster seats", which this model does NOT convert to.Children are not ready to be in a regular lap/shoulder seatbelt until:They are tall enough so that their legs bend at the knees at the edge of the seat; andThey are mature enough to remain seated with their backs flat against the back of the seat and not slouch; andThe lap belt sits high on the thighs or low on the hips (NOT on their tummy!); andThe shoulder belt crosses the shoulder and chest (NOT on their arms or neck!); andEach passenger must have their own lap and shoulder belt! Never allow children to share a seatbelt. Some organizations will also give limits like 80 or 100 pounds, 4'9" in height or 8 years old. These are rough guidelines, not absolute limits. The criteria above are most important.Its only "conversion" is to use the car seat belt rather than the attached seat harness (which you would NOT use with the seat belt). You would need to check the user guide to see how to correctly thread the seat belt thru these staps and at what age and size they recommend using this type of restraint for....
Use of a seat belt is a way to prevent injuries in a collision.
The first modern three-point restraint (integrated lap and shoulder belt) was patented in 1955, though it wasn't standard equipment in the US for many years. In the US, a shoulder belt has been mandatory for the outboard front seats since 1968, though for several years it was common for the lap and shoulder belts to be separate.
a harness is a weight belt that you wear like a jacket
Yes you do. Seat belt keeps you from sliding under the shoulder belt. Shoulder belt keeps your body (and head) from slamming forward into things like the dashboard. Put them both on. If it bothers you, pretend you are flying a jet fighter. Pilots wear them too.
Most Likely: YES. In Ontario Canada, the website states:"A typical seat belt assembly consists of a lap and shoulder belt. The shoulder belt should be worn closely against the body and over the shoulder and across the chest, never under the arm. The lap belt should be firm against the body and low across the hips."There are limited exceptions, they include medical reasons, a firefighter in a firetruck engaged in their work, even being a person in custody in a police car!Where you live, laws of course, may be different. I encourage you to check with your local police or government website.Defeating the purpose of the shoulder belt can be dangerous, it serves to help keep the driver from hitting the steering wheel or the passenger hitting the dashboard during a collision. Airbags are calibrated expecting a passenger IS shoulder belted in. Slamming into an exploding airbag without a shoulder belt to help slow you down first would probably be a (briefly) painful experience!see: http://www.mto.gov.on.ca/english/safety/seatbelt.shtml
