"It took me a long time to discover this vital element about cycling--how posture affects pain outcome--which made me realise how most daily commuters are barely aware of that, if at all!" Haneman's investigations prompted him to try to design an adjustable frame, with the focus on the seat angle
and distance from both the bottom bracket and the handle bar.
It also said that the seat height adjustment links are at risk of breaking or detaching from the seat frame, which could lead to alteration in seat angle
and increase the risk of a crash.
It features a padded seat and backrest, optional armrests, a flexible seat angle
, and a back cutout to allow air flow for student comfort and easy carrying.
For the optimized design, the preferred intake valve seat angle
is between 48% and 52% with a valve seat undercut of 38% to 42%.
Head Angle: 69.5 - Seat Angle

Caregivers also installed seats too loosely (43%), did not use the correct seat angle
(36%), did not lock the safety belt (23%), or spaced the car seat incorrectly related to the front seat (17%).
vertical), recumbent (i.e., seat angle
from 105 to 150 degrees between the backrest and seat) or supine (i.e.
According to the company, the car has the segment defining headroom, width, legroom, and the rear seat angle
ensure comfortable seating.
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 (0.2, 0.3) were varied and the combinations were analyzed.
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
