We all know that many carseats are difficult to use, even for those who take on the daunting task of reading the manual first. Manufacturers do make advances over the years with new and improved designs that make carseats easier to install and use. One such innovation is LATCH, Lower Anchors and Tethers for CHildren, which has now been around for almost 20 years.

Original designs on both carseats and vehicles made LATCH difficult to install, and often even more difficult to uninstall. In particular, automobile manufacturers often did little to improve the location and visibility of their lower anchors and top tethers. Deeply hidden and angled lower anchors were common, and top tether anchors were sometimes too close, too far or extended to odd placements in the roof of an SUV or wagon.

  

In 2015, the IIHS added a rating system for LATCH to their automobile safety evaluations.  This simple addition has provided motivation for automakers to improve their designs.  According to the 2019 LATCH Ratings from IIHS:

Nearly three-quarters of 2019 vehicles have LATCH hardware that rates good or acceptable for ease of use, as automakers continue making improvements that help parents and caregivers properly install child restraints.

The results mark a shift from 2015, when IIHS launched its LATCH ease-of-use ratings. At that time, a majority of new vehicles rated poor or marginal.

Today, 21 vehicles earn the top rating of good+, 33 are rated good, and 88 rate acceptable. Forty-nine vehicles are marginal, and only four earn a poor rating. Among automakers, Toyota and Subaru are standouts for LATCH ease of use, while U.S. automakers lag behind. Installation in pickups remains tricky, compared with other types of vehicles.

For the technically inclined, in the IIHS rating system, LATCH hardware is rated “Good” if it meets the following criteria:

  • The lower anchors are no more than ¾ inch deep within the seat bight — the place where the seatback meets the bottom seat cushion — or slightly deeper if there is open access around them.
  • The lower anchors are easy to maneuver around. This is defined as having a clearance angle greater than 54 degrees.
  • The force required to attach a standardized tool representing a child seat connector to the lower anchors is less than 40 pounds.
  • Tether anchors are on the vehicle’s rear deck or in the middle of the seatback. They shouldn’t be at the very bottom of the seatback, under the seat, on the ceiling or on the floor.
  • The area where the tether anchor is found doesn’t have any other hardware that could be confused for the tether anchor. If other hardware is present, then the tether anchor must have a clear label located within 3 inches of it.

To earn a Good rating, two LATCH positions in the second row must meet all five criteria, and a third tether anchor must meet both tether criteria.

The Good+ rating is for vehicles that meet the criteria for a good rating and provide additional LATCH-equipped seating positions! For a two-row vehicle, that means having a 3rd Good or Acceptable LATCH seating position. The third position may use either dedicated anchors or anchors borrowed from other positions. In many vehicles that have lower anchors in the second-row outboard seating positions, LATCH can be used in the center position by “borrowing” one anchor from each side. Some vehicles have one dedicated anchor for the center seat and rely on a borrowed anchor for the other side.

For a three-row vehicle to earn a Good+ rating, it must have one additional good or acceptable LATCH position (without borrowing) and tether anchors in ALL rear seating positions! The additional tether anchors must meet at least one of the two tether anchor criteria. If the vehicle has a second-row center seating position, it must have good or acceptable LATCH there (with or without borrowing).

Unfortunately, pickup trucks continue to be problematic. Currently, there are no pickups that earn a good rating. Only a few pickups earn an acceptable rating, and most are rated marginal. The problem is the tether anchors. In most pickups, the carseat’s tether strap must be routed through a loop behind the head restraint and then attached to another loop or anchor, typically in an adjacent seating position. It’s VERY confusing!

“When we’ve done studies observing people installing child restraints, we’ve seen that the tether anchors in pickups are a real point of confusion,” Jermakian says. “We’re continuing to work with manufacturers to come up with solutions to this issue.”

Here at CarseatBlog, we would welcome any improvement to the current tether strap routing systems in most pickup trucks. There HAS to be a better way to overcome the challenge of creating more distance between the top of the carseat and the tether anchor attachment point in the vehicle. In the meantime, we do applaud Toyota for adding a diagram to the loop of webbing, so at least it draws attention to itself and provides a clue that it’s supposed to be used for something!
