The Toyota Sienna is a popular choice for disability conversions due to its spacious interior, reliability, and modern features, including its fuel-efficient hybrid powertrain. Leading conversion companies such as BraunAbility and Vantage Mobility International (VMI) collaborate with Toyota to modify the Sienna, integrating various accessibility features.
Common Types of Sienna Mobility Conversions
Toyota Sienna disability vans are commonly available with side-entry or rear-entry conversions, each offering distinct advantages depending on the user's needs.
Side-Entry Conversions
Side-entry conversions are frequently chosen by individuals who wish to drive from their wheelchair or occupy the front passenger seat. Key features often include:
- Lowered Floor: The van's floor is significantly lowered to provide increased headroom and a more gradual ramp slope.
- Power Kneeling System: Many models include a system that lowers the van's side for easier ramp access.
- Ramp Options: Available ramps include power in-floor ramps that store beneath the floor and power or manual fold-out ramps that are stored vertically.
Rear-Entry Conversions
Rear-entry conversions are often a more economical option, particularly suited for situations where the wheelchair user consistently rides in the middle or rear sections of the van. Benefits include:
- Ramp Position: Access is provided via a ramp at the back of the vehicle.
- Original Chassis: The front of the chassis remains largely unaltered, which can contribute to lower conversion costs.
- Parking Flexibility: These vans can utilize standard parking spaces as side clearance for a ramp is not required.
Access Seat Conversions
For those who do not use a wheelchair but have difficulty entering and exiting a vehicle, some Siennas can be fitted with a power rotating lift-up seat. This Toyota-offered feature rotates, extends, and lowers to facilitate easier transfers.
How a Toyota Sienna is Converted
Certified specialists transform a standard Sienna through a multi-step process. This typically involves:
- Replacing the original floor with a lowered one.
- Modifying the suspension system.
- Installing a ramp or lift system.
- Adding interior features like removable seating and securement systems.
