Man sues Bobbi Kristina Brown for severe injuries from January car wreck

A Georgia motorist is suing Bobbi Kristina Brown for severe injuries stemming from a car wreck in January, four days before the daughter of the late-Whitney Houston was discovered unconscious in a bathtub on Jan. 31.

Russell J. Eckerman from Marietta, Georgia, is claiming medical bills and damages exceeding $730,000 from an accident involving Brown on Jan. 27, just days before she entered the hospital.

In legal documents obtained by CBS News dated June 29, Eckerman states that he had multiple spinal fractures, multiple skull fractures and facial fractures, and had to be put in a medically induced coma and underwent extensive surgeries following the accident.

Eckerman states that Brown, 21, was driving a 2005 Jeep Liberty negligently in Fulton County, at an unsafe speed and following too closely in bad driving conditions, when she changed lanes and then lost control of her vehicle. Brown swerved over the center line and collided head-on with the Eckerman's 2007 Ford Taurus driving in the opposite direction, the lawsuit states.

The suit is brought against Brown, who has been in hospice care since last week, through her guardians Bobby Brown and Pat Houston and her conservator and attorney, Bedelia Hargrove.

In the same lawsuit Eckerman is also suing Ford Motor Company for the failure of his seatbelt and air bag to protect him, stating that the parts were "defective" and unreasonably unsafe. He also names a third driver in the crash, Danyela Bradley, for negligent driving as another defendant.

Last week, Brown's conservator Hargrove filed a $10 million civil lawsuit against Brown's boyfriend Nick Gordon for domestic abuse leading to her current near-death condition, and claiming he embezzled and manipulated Brown. Gordon has been assembling a high-powered legal team including Jose Baez who had successfully defended Casey Anthony against murder charges of her daughter Caylee.

"Defendant Brown was traveling at an imprudent speed for conditions and was following too closely and improperly attempted to change lanes in order to avoid the vehicle stopping in front of her," the lawsuit claims. "Defendant Brown lost control of the vehicle she was operating crossed the center line and collided with Plaintiff's vehicle causing extensive damage to Plaintiff's vehicle and serious personal injury to Plaintiff."
