Necessity of Ergonomics Seats?
Drivers are frequently exposed to shocks when their vehicles encounter irregularities. Shocks are transmitted to the driver when the seat suspension runs out of travel. Exposure to shock increases the risk of spinal injury and lower back pain for drivers.
What is Antropometry ?
The branch of ergonomics that deals with the human variability in size, shape and strength. Design of Ergonomic Seats are based on this property. Human factors must be taken into account for every person who comes into contact with the product, during manufacture, maintenance and repair, or disposal.
Correct Dimensions of Seats as per Ergonomic Designs
Optimum seat height is close to the popliteal height of the user.Increase of height above this level can cause severe pressure on the underside of thighs.Decrease of height below this level compromises only with a greater leg room for the user.Also experiences great problems during standing up and sitting down.
Deeper the seat, greater are the problems of standing up and sitting down. Also user will not be able to engage the backrest effectively without unacceptable pressure on the backs of knees. Tall people sometimes complain that the seats of easy chairs are too short.
Higher the backrest, more effective it will be in supporting the weight of the trunk.Three varieties of backrest; low level, medium level and high level backrest.
LOW LEVEL BACKREST
It provides support for the lumbar and lower thoracic region only.It allows freedom of movement for shoulders and arms.Old fashioned typist chairs
MEDIUM LEVEL BACKREST
Supports the upper back and lower back regions.Most modern seats fall to this category.
HIGH LEVEL BACKREST
Gives full head and neck support.
ROLL OF SEAT ANGLE
A positive seat angle helps the user to maintain good contact with the backrest.It helps to counteract any tendency to slide out of the seat.
ROLL OF ARMRESTS
Armrests give additional support for standing up and sitting down. It supports the fleshy part of the forearm. An elbow rest 200–250 mm above the seat surface is generally considered suitable.
