Sentences with phrase «head restraint geometry»

Starting points for the ratings are measurements of head restraint geometry — the height of a restraint and its horizontal distance behind the back of the head of an average - size man.

Even as automakers improve head restraint geometry, many motorists aren't reaping the full benefits.

In 1995 the Institute began to rate head restraint geometry, finding only 3 percent of vehicles had good head restraints while those in 82 percent of new passenger vehicles were poor (see Status Report special issue: whiplash injuries, Sept. 16, 1995).

Seats with good or acceptable head restraint geometry then are tested dynamically on a movable platform using a dummy that measures forces on the neck.

The test procedure applied by Euro NCAP therefore promotes the best practice in seat design, in particular good head restraint geometry, its ease of use as far as adjustment, the locking of the head restraint and the overall seat integrity.

Good head restraint geometry doesn't guarantee good occupant protection in rear - end crashes, but it's an important first step.

«But good head restraint geometry by itself isn't sufficient,» Lund says.

Starting points are measurements of head restraint geometry — the height of a restraint and its horizontal distance behind the back of the head of an average - size man.

Recognizing improvements in head restraint geometry and the need to move beyond ratings based solely on geometry, Institute researchers joined with other whiplash injury prevention experts in late 2000 to organize the International Insurance Whiplash Prevention Group (IIWPG).

IIHS evaluates the geometry of head restraints in passenger vehicles based on the height and backset relative to an average - size male.

This guarantees that nearly all new head restraints would be rated good for geometry by IIHS.

Seats and head restraints with geometry rated good or acceptable are tested in a simulated rear impact conducted on a sled.

Good geometry is essential for an effective head restraint.

The Institute doesn't test seats with head restraints that are rated marginal or poor for geometry because such seats can not be positioned to protect many taller people.

«Still it's encouraging that the seat / head restraint combinations in only 7 of the models we evaluated didn't make it to the dynamic test because of marginal geometry,» Lund says.

All of these seat / head restraint combinations earn overall ratings based on both geometry and dynamic test results.

This means the geometry of a head restraint has to be adequate, and so do the stiffness characteristics of the vehicle seat and head restraint.»

«Automakers are improving the geometry of their head restraints, compared with the last time we evaluated them,» says Institute chief operating officer Adrian Lund.

«To accomplish this, the geometry of a head restraint has to be adequate, and so do the stiffness characteristics of the vehicle seat.

At full vertical adjustment, the front head restraints are high enough and close enough to the back of the head for adequate geometry.

Seat / head restraint combinations with good or acceptable geometry are tested dynamically using a dummy that measures forces on the neck.

The geometry is assessed to see whether or not the head restraint can be positioned to prevent excessive head movement and provide effective support.

Auto manufacturers are improving the designs of head restraints, partly in response to the Institute's consumer ratings of restraint geometry by vehicle make and model (see «Head restraints: Geometry improves, and some have advanced designs,» Oct. 6, 20head restraints, partly in response to the Institute's consumer ratings of restraint geometry by vehicle make and model (see «Head restraints: Geometry improves, and some have advanced designs,» Oct. 6geometry by vehicle make and model (see «Head restraints: Geometry improves, and some have advanced designs,» Oct. 6, 20Head restraints: Geometry improves, and some have advanced designs,» Oct. 6Geometry improves, and some have advanced designs,» Oct. 6, 2001).

A straightforward approach is to improve the geometry of the restraints so they can be positioned behind and closer to the backs of most occupants» heads.

The researchers identified 2,641 property damage liability claims for rear - end crashes of the cars included in the study — Taurus and Sable models with and without improved restraint geometry, Volvo S70s with and without WHIPS, Toyota and Lexus models with and without the WIL system, plus a number of Buick, Nissan, Pontiac, and Saab models with and without active head restraints.

The geometry of the head restraints in many cars, including the 1999 Ford Taurus, is inadequate.

As more restraints with good geometry are introduced and the number of active head restraint systems increases, there's a need for dynamic testing to assess the overall performance of seats and head restraints in reducing whiplash injury risk.

Only five passenger vehicles have head restraints with good geometry; more than half of the restraints are poor,» April 12, 1997).

Improved geometry: Some vehicle models that used to have head restraints rated poor now are being equipped with good or acceptable restraints.

Good geometry is the necessary first step in assessing static head restraints, but seat characteristics such as stiffness also can influence whiplash injury risk.

The Institute doesn't test seats with head restraints that are rated marginal or poor for geometry.

«It's encouraging that only 12 of the 58 seat / head restraint combinations we evaluated didn't make it to the testing stage because of marginal or poor geometry,» Lund says.

This test uses both geometry and dynamic ratings to determine if a head restraint is effective.

In the first step restraint geometry is rated using measurements of height and distance from the back of the head of a mannequin that represents an average - size man.

Seat / head restraints with good or acceptable geometry are tested dynamically using a dummy that measures forces on the neck.

The Insurance Institute for Highway Safety began rating the geometry of head restraints in 1995, finding only 3 percent of vehicles had good head restraints, while those in 82 percent of new passenger vehicles were poor.

Head restraints with poor geometry can not be positioned this way for many occupants, so they can not begin to prevent whiplash injuries.

With or without federal action, head restraints already are being improved — and geometry isn't the only aspect that's getting better.

To accomplish this, the geometry of the head restraint has to be adequate, and so do the stiffness characteristics of the vehicle seat.»

Active head restraints are designed to automatically improve head restraint position and / or geometry during a rear - end impact by moving towards the head of the occupant.

Head restraints with good geometry can reduce neck injuries; restraints in most cars don't have good geometry, wouldn't protect most people in rear - enders
