Thread: Installing Britax Frontier in harness mode w/seatbelt

No, the 30-40 degrees is the angle of the back (well, where the baby's back is) to the ground. The seat has two positions, upright and reclined, and it must be reclined rear facing. When you put it in the backseat of an Xterra it'll go very upright. You'd need a noodle or five for a newborn (I needed five noodles for my newborn in my Xterra), but at 10 months you can use no noodles, or just one or three (generally odd numbers...

As far as I can tell, it is infinitely adjustable. There is a knob you turn that moves the head wing/harness piece up and down as you turn it. The manual does not give a lot of guidance for the harness slot position rf. It does state the harness straps should be "at or slightly below" the shoulders. For ff, it specifies that the line drawn between the harness slot and the child's shoulders to determine relative position...

It is infinitely adjustable. The straps do not need to be below her shoulders. *At* her shoulders is the correct position for an infinitely adjustable harness.

It's because of the shoulder belt. The shoulder belt pulls up on that side of the base, and over time, it tips. Very common. The solution is usually to reinstall, using a locking clip (or lockoffs if your base has them) and leave the shoulder belt unlocked.

With the way it was offset, I did not think it would work. Seat belt would be the easiest way.

I guess it just seems so reclined to me because I'm not used to having 2nd row reclining seats, and I prefer to sit pretty upright in the car. It will certainly help her sleep even better in the seat though, because there is no way at that angle that she'll head-flop. I made my DH get out of bed to pull...

After I'd tighten, and push the lever down it would stay (until it got lifted again). I thought maybe it...

If the car's manual says not to touch front seatbacks plural, then it would preclude a rear facing seat touching the driver's seatback as well as the front passenger seatback so I'd double check that out carefully. It's entirely possible there are sensors that affect the force of driver's side airbag deployment, especially if there are side torso airbags mounted on the driver's vehicle seat. FWIW, the wording is...

Yep, any locking clip will do. Good luck!
