Convertible Car Seat FAQ’s

Q: What Are The Basic Guidelines For Proper Safety Seat Use?

A: Install the security seat so that it does not move more than an inch to the front or sides of your car.

  1. You need to also thread the straps below your kid’s shoulders on a rear-facing seat and through the top-strap in forward-facing convertible seats. Belts SHOULD be above your infant’s shoulders in the positions that only face forward, such as the combo-seats.
  2. Another critical factor is that your harness should not only be snug but also tight enough.
  3. You need to ensure that the top of the harness clip should be at the armpit base.
  4. Also, place any coats on top of the seat’s harness.
  5. Another factor is that you need to restrain your kids in the rear seat, more so if your vehicle possesses a passenger airbag. You must never put a rear-facing safety seat in front of a passenger airbag.
  6. Finally, use a top tether with forward-facing safety seats, attached to a designated tether anchor. It can reduce the forward motion of your baby ’s head in a crash by several crucial inches.

Q. Is It Secure For A Baby To Travel In The Front Seat?

A: No. It is more secure for your little angel to travel while in the rear seat. The most sheltered spot for your baby should is in the backseat. Thus, if you have the option, place your infant in the back position.

It is safe to put him or her in the middle spot of your back seat, away from the vehicle’s airbags. If the middle of the back position has a three-point seat belt, then that is the safest place to place a child restraint. It is always the furthest place away from the sides of your car.

However, if it only consists of a lap-only belt, check out the infant’s seat instructions to see you can fit it with a lap-only belt. If not, then you need to secure the seat on either side of the rear seat using the lap and a diagonal belt.

Q: What Is A LATCH?

A: The LATCH refers to Lower Anchors and Tethers for Children. It is an ‘Infant Car Seat Installation System,’ where you attach the lower hooks between the bottom of the back of the seat and the seat itself. The tether piece is a strap made of seat belt material with a clip that secures forward facing baby car seats and eliminates chances of excessive movement of the infant’s head in crashes.

Convertible Car Seat Summary
