For the optimized design, the preferred intake valve seat angle
is between 48% and 52% with a valve seat undercut of 38% to 42%.
Accurately: Similar to the KeyFit and KeyFit 30 Infant Car Seats, the NextFit makes it easy to achieve an accurate installation with the two RideRight (TM) bubble levels, which clearly indicate the correct seat angle
in both rear- and forward-facing modes.
The three influential parameters, seat angle
(30[degrees], 35[degrees], 45[degrees]), cone angle (0[degrees], 10[degrees], 20[degrees]) and fillet radius to diameter ratio (0.
The model features rear seats that can adjust forwards and back by up to four inches and both legroom and the seat angle
may be set to the preferences of the passengers.

The Romer Duo is designed to be fitted in the rear seats, positioned in a forward-facing position, is for children 9kg to 18kg and has three seat angle
To design a bent bike specially built for speed, Too experiments with the seat angle
and height, and leg distance to the pedals.
: The seat angle
should allow users to vary their posture forward and backward.
Also, a relatively upright seat angle
means legs are uncomfortably bunched up - not ideal on long journeys.
Adjusting the seat angle
by a 10 to 15 degree tilt downward alleviated pain for 70% of the cyclists.
When the seat angle
exceeds 60 degrees from vertical, the dummy can move up the back of the seat, with the potential for secondary impact with the car interior.
The analysis also showed secondary factors contributing to the pressure loss across the valve including high peak velocity at the seat angle
, and the unequal and irregular velocity distribution and deceleration in the top and bottom diffusers.
